What is ReactJS? 

ReactJS is a JavaScript library, which is easy to learn, reusable, fast, and responsive. It is touted to be the best option for building single-page applications of any scale and size. With all these attributes playing out in its favor, ReactJS is all set to dominate the developer community, job market, and technology landscape.  Data suggests that ReactJS adoption is nothing less than a wildfire. With a lot of big names under its belt who have already migrated or in the process the growth rate of ReactJS is likely to only go higher in the coming years. Besides Facebook, React JS is used by digital pioneers like Uber, Airbnb, Netflix, Amazon, Instagram, Twitter, Shopify, Microsoft, WhatsApp, Atlassian, Codecademy, Dropbox, New York Times, Asana, Intercom, Slack, Storybook… the list goes on. 

Furthermore, ReactJS is among the Top 5 Digital Skills that companies are looking for when hiring developers. The open positions for ReactJS developers grew by a whopping 184% last year compared to 2019. Smart developers know this and are fortifying their skills with ReactJS.  According to Statista, JavaScript is a choice of 67% of developers, and ReactJS is the first choice of developers between all the JS frameworks.

Data doesn’t lie: ReactJS- Most Used & Loved Framework

To put it in simple words, front-end developers just love ReactJS. In fact, in a recent survey done by Stack Overflow ReactJS was voted as the most loved framework by developers.

Another report suggests that over 71% of developers who have used ReactJS want to use it again.

According to the below chart from the State of JavaScript report, which shows each technology’s ratio of satisfaction over its user count, in four quadrants: 

• ASSESS Low usage, high satisfaction, worth keeping an eye on. 
• ADOPT High usage, high satisfaction, technologies safe to adopt. 
• AVOID Low usage, low satisfaction, Technologies to avoid
• ANALYZE High usage, low satisfaction, Reassess, is already using it. 

ReactJS falls under the ADOPT quadrant (High usage, high satisfaction. technologies safe to adopt). It is not a surprise that ReactJS has garnered 164.1K GitHub stars by the developer community. At the same time, over 9000 companies use the framework in their tech stacks.

ReactJS- Raging Popularity as Web App Development

Before anything else, let us answer the big question –  what are the factors behind the raging popularity of ReactJS? 

1. Very Easy to Get Started

Thanks to its simple design, use of JSX which is very HTML-like syntax for templating, and highly detailed documentation. Add a small little code generator to the mix and things start to fly, isn’t it? 

2. Reusable Code

Developers spend more time writing JavaScript business logic rather than worrying about the framework-specific code.

3. Fast and Responsive

Owing to the virtual DOM implementation and various rendering optimizations the memory data structures in ReactJS are converted to components. These ReactJS components update and modify the browser by running the computation tasks. VDOM renders these components, data, and elements so that they can be processed and utilized further.

4. Server-Side Rendering

Great support for server-side rendering, making it a powerful framework for content-focused applications. fewer browser compatibility issues, data security, and less loading time. 

5. One-way Data-Binding

Redux, the most popular framework for managing application state in React, is easy to learn and master. Some values can be passed as components and rendered in HTML tags as properties. But, it is difficult to change and access them directly. However, ReactJS allows developers to access components and directly change them by enabling the call back function. This ReactJS property is referred to as properties flow down and actions flow up. 

6. Type Safety

Microsoft’s TypeScript or Facebook’s Flow has native support for JSX and can help in making applications type-safe.

7. SEO Friendly

Applications built on ReactJS are SEO friendly, helping in higher discoverability and visibility of the apps.

8. Native Applications

ReactJS lets developers build Native Mobile Applications by reusing code-With ReactJS you can, not only build high-end Web Applications but also develop Native Mobile Applications (iOS and Android), by using the same code which can be modified with the help of React Native. 

Benefits of Choosing ReactJS vs AngularJS or Vue.js

There are approximately 24 JS frameworks. Most popular being ReactJS, AngularJS and Vue.JS. So, how does ReactJS compare to AngularJS and Vue.js? Here’s a quick overview:

AngularJS

 Angular is the oldest in the race for JavaScript MVVM framework, founded in 2009, which is awesome for building highly interactive web applications. So, you can also hire AngularJS developers to fasten your development work. 

Benefits of AngularJS 

• Angular is created to be used alongside Typescript and has exceptional support for it. Thus, the strong type support makes the framework pretty robust to work with. 
• AngularJS boasts of some new features like Angular-based npm libraries from CLI, generation and development of Angular-based Web Components, etc.
• AngularJS has detailed documentation that empowers the developers with all the necessary information.
• It enables singular behavior i.e., one-way data binding, thus the app resulting in minimized risks of errors. 
• The MVVM model (Model-View-View Model) enables developers to use the same set of data and work independently on the same section of the app.
• Dependency injection of the features related to the components with modules and molecularity in general.
• The AngularJS structure and architecture is specifically designed for enhancing scalability of flexible projects.

Drawbacks of AngularJS: 

• It can be difficult to learn in comparison to the other options in the comparison. 
• Relatively slower performance, according to different benchmarks. 

AngularJS vs ReactJS

• ReactJS supports Unidirectional data binding and AngularJS support Bi-directional data binding.
• Compared to ReactJS, AngularJS is difficult to understand. The reason is the support of third-party syntax and libraries.
• ReactJS is an Open Source Framework while AngularJS is an MVC framework.
• ReactJS works on Virtual DOM and AngularJS works on Regular DOM.

Vue.JS 

Vue.js, a JavaScript framework, was launched in 2013. It is a flexible framework with advanced web tools to develop modern SPAs (single-page applications) and front-end web apps.

Benefits of Vue.JS: 

• Detailed Documentation-  Vue.js has very clear documentation which can shorten the learning curve and makes it easy to start. 
• Familiar Interface- It provides a rapid switching period from other frameworks to Vue.js because of the similarity with other frameworks. 
• Better Integration- This framework can be used for developing both single-page applications and also complex web app interfaces. 
• Focus on scaling to develop pretty large reusable templates. 
• Tiny size- Vue.js is a lightweight framework of around 20KB.  As a result, it is a fast and flexible framework that allows for efficient performance.

Drawbacks of Vue.JS: 

• A small developer community and lack of support make it hard for developers to find solutions to problems.
• While enterprises like Xiaomi and Alibaba have adopted Vue.js and it has helped in popularizing the framework. The popularity ratio remains higher in China and a major part of the content and discussion around the framework is in Chinese.
• Vue.JS has a two-way data binding for managing DOM updates. The issue with the reactivity system is that it renders only the chunks of data that were triggered and often makes mistakes during data reading, which requires data to be flattened.

 Vue.JS vs ReactJS 

• Vue uses HTML templates while React uses JSX. JSX or JavaScript Expressions is integration of CSS and HTML into JavaScript. It is an XML-like syntax that enables developers to develop UI components that are self-contained along with view-rendering instructions.
• Apps built on React have faster performance than the ones built on Vue. The addition or extension of a component makes the Vue app slower to load.
•  ReactJS caters to the view layer of an application that is made up of components and Since doesn’t have a built-in architecture pattern. Vue follows the View Model approach and undertakes the pattern on MVVM especially while developing a large-scale application.

In Conclusion:

A lot of factors are involved while choosing the best framework for web app development. Speed, performance, stability, affordability are a few variables that make ReactJS a perfect choice for the development of web apps, especially for large-scale enterprises. No wonder, even giants like Twitter, Instagram, Netflix, trust this framework.  These frameworks are evolving at a faster rate and are in close competition with each other. For the success of any app, the best technology and design have to come together.

Given the ever-evolving landscape of technology it can be difficult for enterprises to have skilled resources in all these areas.

The post Why is ReactJS the Perfect Choice for Web App Development? appeared first on EngineerBabu Blog.

AngularJS development has been used to build many renowned and heavy traffic websites such as Gmail, Google, Paypal, Netflix, Virgin America, and many more. It is based on the MVC model (Model View Controller) and is a great framework to develop Single Page Web apps.

AngularJS can handle DOM and AJAX on its own instead of coding them and is the major benefit of using this framework. It also provides various tools for developers to deliver modular building blocks by mix match and test code. The developers can also add an HTML page just by using a few simple tags.

Though Angular provides superfast performance by default, while designing complex and realistic applications, it shows some problems and affects the performance of your application. The reason for such a suspicious performance can arise by not following best practices by the team of developers.

As a result, it requires to optimize AngularJS applications that can tackle the threat over its performance. So, now we will learn some tips to optimize AngularJS performance to get the best performing application. But before that, let’s know more about AngularJS development.

What is AngularJS?

AngularJS is a structured, open-source JavaScript framework used for building dynamic single-page applications. It is a web framework that uses code templates written in HTML to carry-out a particular command or function. It was developed in 2009 by ‘Misko Hevery’ at Brat Tech LLC. Now, it is maintained by Google.

AngularJS has data binding and dependency functionality, which saves time from writing lengthy codes. All such features are packaged in a browser and make it the most suitable server technology.

There is a hands-on difference between a Static document and a Dynamic Application. Therefore, the Dynamic Application usually prefers libraries and a framework that supports the development of web apps. At the same time, the library held a number of functions that are used to perform specific operations. These frameworks automatically fetch the data and call the relevant function when required. AngularJS can create new HTML constructs that, in the end, eliminate this mismatch effectively. Hence, it creates new syntax with the help of these directives.

Concepts of AngularJS

AngularJS framework works on the following terminologies or concepts in web app development.

1. Modules

Modules are defined as a container that collects or holds various parts of an application. Basically, a Module is a set of functions defined in the JavaScript file. A module is very useful and works perfectly in dividing an application into small and reusable components.

2. Expressions

The Expressions in AngularJS are expressed with {{ }}, and it indicates the data binding in HTML. Such expressions are added to the HTML templates. However, the Expressions do not support control flow statements while supporting the filters.

3. Directives

Directives indicate the compiler to relate a behavior with the DOM element or modify it. AngularJS framework has several directives such as ng-if, ng-view, ng-app, ng-controller, etc.

4. Controller

The Controller is a JavaScript object constructor function. Basically, it controls the AngularJS web or mobile applications.

5. Scope

A Scope is a JavaScript object that acts as a bridge between the View and the Controller. Overall, it is the source of data in AngularJS. With the help of the Scope object, each assignment and data manipulation takes place.

6. Validations

Validation takes place with the help of AngularJS controls and forms.

7. Data Binding

Data Binding coordinates to view and model about any changes in any of these two.

8. Services

Services are the singletons that are used by controllers, directives, and other services.

9. Filters

Filters allow you to display the data formatting on DOM, and it also extends the behavior of directives and binding expressions. These filters format the values or apply them specifically.

10. Dependency Injection

Dependency Injection is a designed pattern that is used to handle dependencies of numerous components of the software. It also allows the loosely-structured architecture development.

11. Routing

The service of $routeProvider manages all the operations of Routing. It effectively divides the map into multiple views. Routing helps to split the Single Page Applications into different views.

12. Testing

The codes are getting tested, which are developed by the Dependency Injections. Whereas some of the popular testing frameworks are Jasmine and Karma, these two are the majorly used technologies among AngularJS developers.

Advantages of AngularJS

• It is quite easy to work on and learn the AngularJS With a few simple modifications, you can achieve the benefits of AngularJS in minimum time.
• AngularJS allows two-way data binding, enabling view and model to coordinate with the changes among one another.
• With AngularJS, the developers don’t have to go with observable functions. It automatically analyzes the DOM and creates the binding on the basis of Angular-specific element attributes. This saves developers time from writing lengthy codes.
• Most of the framework requires the developer to divide the application into multiple small components or MVC components and then write codes to join these components. Whereas AngularJS is capable of solving this issue easily, as it combines the components automatically.

Disadvantages of AngularJS

• The AngularJS applications are not safe. Such applications require server-side authentication, and it is necessary to maintain the security of the application.
• If the application user disables the JavaScript, then in the application, nothing gets displayed except the basic page.
• Sometimes, AngularJS becomes quite complex to handle it. As there are multiple ways to perform the same task, and it results in confusion. Hence, it requires considerable effort to manage a task.

Tips to Optimize AngularJS Performance

There are many built-in tools to optimize AngularJS, but the performance issue still shows pores in the framework. While working with AngularJS, if you don’t have a massive infrastructure like Google, then you need to implement some preventive measures or the best practices to optimize AngularJS performance to boost the application.

Before heading towards the tips to optimize AngularJS, it is suggested to always look for the room of improvement to boost performance despite the feeling that you don’t need that. So, here are the following few tips to speed-up or optimize your AngularJS apps.

1. Carefully Observe your Digest Cycle to Optimize AngularJS

The digest cycle is considered as the best indicator of AngularJS applications performance. It is a cycle that works on a loop to check and monitor the changes in the variables. Hence, as much shorter the digest cycle is, the faster your application will run.

It will definitely boost the performance of the application and deliver good results from the customers. A fair performing application will automatically attract more users and give a boost in the market.

2. Limit your Watchers to Optimize AngularJS

Implement data-binding at any time, and with this, you can create more $$watchers and $scopes, which will extend the digest cycle. Too many $$watchers can increase lag time, therefore prefer limited use of it or avoid using it as much as possible.

As we learned in the above point, the small digest cycle will result in an optimized AngularJS performance. Hence, make sure to limit your watchers and prevent long digest cycles.

3. Limited DOM Access

The access of DOM is quite expensive, so try to maintain the DOM tree smaller. If it is possible, then don’t try to modify the DOM and don’t set an inline style to avoid the reflow of JavaScript.

Limited DOM access can optimize AngularJS performance and minimize the expenses too.

4. Use ‘scope.$evalAsync’ to Optimize AngularJS

While the digest cycle is already running and you try to activate it manually, then you are going to get an error. Therefore, to prevent yourself from this situation use “scope.$evalAsync” instead of $apply, to initiate the digest cycle manually.

This code queues up the operation to be executed at the end of the current cycle without setting off the new or current one. It will save you from getting errors and increase the lag time of the digest cycle.

5. Use the Chrome DevTools Timeline and Profiler

Chrome’s both the DevTools Timeline and Profiler can help find bottleneck situations and perform a guide to optimize efforts. Both the tools work effectively to optimize AngularJS application or web performance.

Chrome DevTools or Chrome Developer Tools are web authoring and debugging built into the browser. It provides access to web browsers and applications to the developers for deeper access. These tools allow developers to perform numerous tasks ranging from testing the viewport on the mobile device to editing the website or even measure the performance of any individual asset or the whole website.

6. Use Lodash to Optimize AngularJS

The Lodash tool in AngularJS allows developers to quickly write application’s logic to improve the built-in AngularJS methods and enhance the application’s performance. However, suppose the Lodash tool is not used in the already existing web application to optimize its performance. In that case, the developers can rewrite the method on their own by using native JavaScript.

This tool allows developers to optimize AngularJS web application performance apart from that they can write the method on their own to do so. It is a very effective tool for AngularJS development.

7. Disable CSS Class and Comment Directives

While creating a directive, the developers can assign it to be used as an attribute, element, comments, or CSS class. However, if you don’t require comment directives and CSS class, it can disable them to boost the AngularJS application’s performance and optimize AngularJS performance.

8. Prefer using One-Time Binding only

In the latest version, i.e., Angular 4.0, this feature is not available. However, if you are using older versions than this, then you may be able to take advantage of on-time binding.

So, to implement or exercise this feature, just add a double colon before the value. If it is done correctly, the value will get resolved once and disappear from the watchers list. This feature was first introduced in the version of AngularJS 1.3, and is not available in the latest 4.0 version.

9. Disable Data Debugging

The Batarang and Protractor tools depend on the data binding and scopes with which AngularJS attaches to DOM elements. Therefore, after finishing debugging, try to disable the extra data so that it doesn’t drag the application performance.

Disabling the data debugging optimizes AngularJS performance and increases the performance of the web application.

10. Avoid ‘ng-repeat’ to Optimize AngularJS Development

Excess use of ‘ng-repeat’ directive can drastically affect the overall performance of the web application. However, to minimize its effect, there are alternatives too. For Example,  instead of using ‘ng-repeat’ to render the global navigation, the developer’s can build their own by using the ‘$interpolate’. It is a provider to render the template against an object before converting it into a DOM node.

11. Use ‘ng-if’ or ‘ng-switch’ instead of ‘ng-show’

The directive ‘ng-show’ simply toggles the CSS display on or off for a specified element.

To remove an element from the DOM, the developers must use ‘ng-if’ or ‘ng-switch’. It is another brilliant tip to optimize AngularJS web applications.

12. Use ‘$cacheFactory’ to Optimize AngularJS

If you need to store the data that might be required to be calculated after a period of time, then prefer using the ‘$cacheFactory’ directive. It is quite similar and works like any other memoization method.

13. Use ‘console.time’

While facing any issue in debugging, ‘console.time’ tool in Chrome DevTools is a wonderful option or tool for calculating the execution time and other performance benchmarks.

It is a brilliant and very helpful tool in managing issues while debugging and calculating different performance benchmarks to optimize AngularJS development.

14. Use $filter to Optimize AngularJS

AngularJS development in a web app runs the DOM filter twice during each digest cycle. In the first DOM filter run, it detects changes, and in the second run, it updates the values that have changed. However, to save time in this whole cycle process, the $filter provider allows pre-process data before it is sent to the View and, after that skip the DOM parsing process.

It is a great tool to optimize the speed of the web application and the AngularJS development process to save time and improve application overall efficiency.

15. Use ‘$watchCollection’

While using $watchCollection, only two parameters are a great choice, but three or more than three parameters are like a crowd. The addition of a third parameter forces AngularJS to go through a deep checking and results in the requirement of a lot of resources in use.

The developers can include excellent work with having around the ‘$watchCollection’. It works as a third parameter for $watch. Despite that, it checks the first layer of each object’s properties, so that it won’t slow down the overall speed and performance of the AngularJS web applications.

16. Debounce ‘ng-model’

Debouncing inputs by using directive ‘ng-model’ can play a vital role in limiting the digest cycle.

For Example, implementing ng-model-options=”{debounce:200}” can ensure that the digest cycle doesn’t run more than once in every 20ms. It is a great tool to limit the digest cycle and ultimately optimize the performance of the AngularJS development.

17. Rigid Scoping

Try to keep all your variables scoped tightly. With this, JavaScript garbage collectors will free up the memory that is getting occupied uselessly and in a frequent manner to fasten the process. It will help provide the required resources to the upcoming processes and speed up the application’s working. It is a very easy and common way to optimize AngularJS performance.

18. Infinite Scrolling or Pagination

It is a very effective and brilliant optimization strategy as if everything fails; then it will work. You can minimize the number of looped elements by implementing the Infinite Scrolling or Pagination technique. To serve this purpose, AngularJS has a directive called ‘ngInfiniteScroll’.

19. Use Pure Pipes to Optimize AngularJS

AngularJS uses pipes to display model values on the UI in a little different format. For example, ‘date | shortdate’. Here, the shortdate filter will convert date objects in the small format like ‘DD/MM/YYYY’. Pipes are used to slice and dice the data for display purposes. The Pipes are categorized into two parts, i.e., “Impure Pipe” and “Pure Pipe”.

The difference between Pure and Impure Pipe is that Impure Pipe can deliver multiple output for a similar input over time. However, the Pure Pipes means a function that can produce similar output for the same input data.

AngularJS has some inbuilt pipes, and all of them are pure in nature. Therefore, when it is preferred to binding evaluation, each time Angular evaluates an expression and then applies the pipe over it (if exists).

AngularJS Performance and Testing Tools

It is always possible and efficient to adopt best practices from the initial phase instead of going back and implementing changes. Before starting coding, plan carefully about how to limit bindings, expensive directives like ng-repeat, and watchers. Apart from that, there are multiple tools that help to optimize AngularJS performance and are good testing tools.

1. Protractor

Protractor is a very powerful and automated end-to-end Angular Testing Tool. The Angular team developed this powerful tool. Protractor is built with the combination of some brilliant technologies such as Selenium, NodeJS, Jasmine, Mocha, Cucumber, and webDriver.

It allows running automated end-to-end testing with an ease. The combination of technologies boasts all the features. With this, developers can use the Selenium grid feature to run simultaneously on multiple browsers. However, by using Jasmine and Mocha, you can write your own test suites.

2. WebdriverIO

WebdriverIO tool allows controlling a browser or a mobile application only with a few lines of code. It makes the test code look simple, concise, and easy to read. This integrated test runner allows developers to write asynchronous commands in a synchronous manner. Due to which, the developers don’t have to care about how to avoid the racing conditions. As well as it also takes away all the complicated setup work and manages the Selenium session.

3. TestingWhiz

TestingWhiz is one of the most user-friendly test automation tools to optimize AngularJS because of its codeless scripting feature. This tool offers an end-to-end testing solution to test the AngularJS web and mobile applications. Its codeless scripting feature makes this tool popular, especially among the non-programmers.

Conclusion

As we have witnessed, Web Development is changing rapidly due to the introduction of new technologies and updates in the JavaScript frameworks. Hence, to gain maximum benefits from these frameworks, being a developer, you must keep optimizing the application performance on a regular basis. By optimizing AngularJS performance, the developers are also able to get more with less coding.

In React vs. Angular, both React and Angular are the powerful development tools used for single-page and multi-page applications, which often connect to external APIs to receive or send data. They have many similarities but some differences too, which makes it a topic of debate that which one is better in React vs. Angular. 

Source: www.medium.com

Businesses often get into the dilemma of React vs. Angular and find it challenging to choose the right framework for their app. We’re going to check and contrast the two JavaScript frameworks and study each of them to make sure we don’t miss a single piece of data and create a comprehensive and justified choice while choosing a framework. 

In the next 8 to 10 minutes, you’ll know what separates Angular and React from each other, when to choose ‘React’ over ‘Angular’ for app development and the situations where you can benefit from choosing ‘Angular’ over ‘React.’ Let’s end the ‘React vs. Angular’ or ‘React vs. AngularJS’ debate for all. Go ahead and have a happy reading.

1. Source and Origin:

Angular

Angular is a JavaScript front-end framework which is written in TypeScript, for web and mobile development. It was developed by Google and launched in September 2016. Angular (Angular 2.0) is a complete rewrite of AngularJS (Angular 1.0), which was introduced in 2010, and the latest release took place on June 10, 2020. 

React

React, on the other hand, is a JavaScript library for UI development developed and maintained by Facebook and the community. Jordan Walke is the original author who introduced this framework on May 29, 2013. The last stable release took place on March 19, 2020.

2. State Management:

An application uses states in multiple instances. A component describes the UI of an application. What framework does is re-rendering the complete component UI when the data changes. Hence, an application ensures that the data is updated in learning about React vs. Angular. 

React

In React’s handling state, it uses Redux as the solution; the disadvantage here is that the state needs to be stored in multiple parts of the app with passing the data manually around different component tree levels. MobX, another solution offered by the state management library, offers storing only the minimal required state, while the rest can be derived.

Angular

While in the case of Angular, the Redux is not used. Component data is stored in component properties. State changes in some parts can be recognized and reviewed, but in a relatively larger application, it’s tough to track multi-directional tree series of updates. NgRx or RxJS libraries can improve the features and make sure that the data flow is unidirectional.

3. Languages:

React

React framework is based on JavaScript ES6+ combined with JSX script (syntax extension, which makes a JavaScript code resemble that written in HTML). It helps in understanding the code and identifying typos. 

Angular

Angular uses TypeScript, which is a superset of JS explicitly developed for larger projects. The code can navigate easily and typos can be spotted since Typescript is more compact than JavaScript. The code refactoring process also becomes more straightforward and faster. Hence, developers can write cleaner codes.

While React allows the reuse of the code components at distinct levels making it easier to manage the updates; Angular helps developers to write cleaner codes with the more compact Typescript. 

4. App Structure:

Angular

AngularJS comes with a fixed and complex structure consisting of three layers: Model, View, and Controller. It is suitable for experienced developers only. The framework allows developers to break down the app’s code in different files. The files’ links are written in the app directive, which displays the app’s structural logic. Respectively, Angular components are also reusable.

React

The best thing about the structure of React is that there is no “the only right structure.” Developers have the freedom to choose. Every pro has its following con. Having a no fixed structure makes it challenging to design one at the start of each project. React app has a component-based architecture; the components make the code, which is then rendered with the React DOM library. The rendered code is then directed in two ways; functional and class-based.

In React, reusing the existing code allows the developers to apply faster reloading into the process, improving the app performance and enhancing the development speed. The React framework gives you the freedom and flexibility to choose the suitable tools, libraries or repositories, and the architecture or structure for app development. React enables you to build a highly-customized app using only the features and tech stack you require.

5. DOM (Document Object Model):

Angular

Angular uses real DOM, where even if one section of it is altered, the whole tree data structure is updated.

React

On the other hand, React app development uses Virtual DOMS. Since they are lightweight and built on the server, they reduce the browser load. App development companies can easily track and update changes to the VDOM without affecting any other section of the tree data structure. 

Since Virtual DOM is also vastly considered much faster in performance than real DOM, it makes it much better for app development. This is the reason, in React vs. Angular, React ranks over Angular in the context of Document Object Model.

6. Testing:

Angular

Angular provides developers the simplicity of using one tool for the entire project’s testing. Developers use industry-standard tools like Jasmine and Protractor.

React

React requires the use of different tools for different kinds of tests. Developers have to use various tools for different types of testing, like Render testing, Code Testing, component testing, and unit testing. It increases the overall timeline of the app development process and requires more effort from the developer’s end.

Hence, Angular wins the React vs. Angular debate in terms of testing.

7. Learning Curve:

Angular

Angular has a steep learning curve due to its vast library, and learning all the concepts takes much more time as compared to the React. Angular IO framework offers different ways to solve a specific problem. It has a complex component management system, and it is essential for developers to be familiar with different concepts and languages like TypeScript, templates, dependency injection, RxJS, etc.

The framework core embeds some complicated features, which limits developers to use them before learning them. Besides, the framework is continuously developing – making it essential for the developers to check out the latest Angular ecosystem updates and upgrade their skill set accordingly.

React

React is minimalistic: no vast library, no dependency injection, no classic templates, no overly complicated features. Though it might take some time to learn how to set up a project because there is no predefined project structure, yet it’s worth it as the overall development cycle is reduced. Prior knowledge of JavaScript makes the framework simple to understand. It would be helpful if developers learn the Redux library, which is used in more than half of React applications for state management. 

Source: www.inflexion.com

Reactjs allows you to quickly learn and develop a mobile app in the React framework if you are well-versed in JavaScript. ReactJS provides various constructive resources and assets to the developers to get familiar with the framework and develop an application with the same. It is for these reasons; developers tend to choose to React over Angular. So it’s clear that in React vs. Angular based on the Learning Curve, React is better than Angular.

8. Data Binding:

React

React uses one-way data binding in which allows the UI elements to be changed only when the model state is being changed. The developers’ limitation using React is that they cannot alter the UI elements without updating the corresponding model state.

Angular

Whereas, Angular uses a two-way binding approach for mobile app development. Bidirectional data-binding negatively affects the performance of Angular apps. The reason being, each of the binding is assigned a watcher to track changes, and each loop continues endlessly until all the watchers and associated values are checked. Hence, more bindings create more watchers, making the whole process cumbersome. The only good thing about the bidirectional approach is that model state changes automatically with the changes in UI elements and vice-versa.

Angular’s approach might seem easy and productive, but in the long run, React offers a streamlined data overview of larger app projects. Thus, in the context of Data Binding, React wins over Angular in the React vs. Angular debate.

9. Development Speed and Productivity:

Angular

Due to its CLI, Angular offers better development experience – and empowering the creation of a workspace and design functioning applications. Angular focuses on producing components and services with one-line commands, built-in process to solve comprehensive problems and clean coding features.

React

In the case of React, the development speed and productivity are affected by third-party libraries’ involvement. The React JS app developers need to put extra time in determining the right architecture for the app, along with the component tools. 

The toolkit for React mobile app development varies from one project to another; it means more time is consumed if the project is to be handed over to new developers for new updates.

Hence, in React vs. Angular, Angular takes over React in development speed and productivity.

10. UI Components:

React

There are many free as well as paid UI components developed by the community on the React portal. The problem with React lies in the installation of an additional library to use material design components to React. Material-UI Library & Dependencies make React a less preferable choice for app development in terms of UI components.

Angular

Angular is embedded with a built-in Material toolset, which offers a wide variety of pre-built material design components for app development. There are various layouts, buttons, pop-ups, indicators, and form controls. This makes the UI configuration simpler and faster.

Angular clearly wins the ‘React vs. Angular’ war when it comes to UI components.

11. Self-Sufficiency:

React

React is a framework for UI development, which isn’t self-sufficient in itself. Apps written with the React framework requires additional libraries as well. Redux, React Router, or Helmet revamp state management processes, routing, and API interaction. All these functions, like component-based routing, data binding, dependency injection or project generation, couldn’t work without installing additional libraries or modules.

Angular

Angular, on the other hand, is quite a self-sufficient framework for app development. It generally does not need additional libraries or modules to carry out some of its essential functions. The angular package comes as a full-fledged package. The functions like component-based routing, data binding, form validation, project generation, and dependency injection – can be implemented within the Angular package without installing any additional libraries. 

When it comes to React vs. Angular, the latter is a complete software development framework in itself that does not require the inclusion of any additional library. Therefore, the vote goes to Angular in terms of Self-sufficiency.

12. Directives:

React

React gives relief by explaining templates and logic at one place – at the end of the component. The best thing about React is that logic and templates in React are explained at the end of every component. This facility enables the readers to understand the meaning of the code even without having to know its syntax. 

Angular

In the case of Angular, the syntax is complex, and it makes it difficult for a reader to comprehend who doesn’t have any prior experience working with this technology. Under Angular, each template is returned with an attribute – a directive of how the object has to be set. 

The complex syntax of Angular’s makes it incomprehensible for the new developers, and therefore in React vs. Angular comparison React is preferred over Angular when it comes to directives.

13. Popularity:

As per Google Trends, React has more searches than Angular. While people show more interest in Angular due to the availability of ample ready-made solutions, both the technologies are developing, which means both are popular in the market. So for now, the answer to Angular vs. React popularity would be equal on both sides, i.e., Angular popularity = React popularity (at least in the current time). 

React

React is an extensively used framework, used for software development (both web and mobile app). However, Mobile app development requires it to be incorporated with Cordova. 

React is known for its multiple uses; for example, it can be used to build both single-page and multiple-page web applications. Moreover, for mobile app development, there is an additional framework – React Native.

Angular

Angular is suitable for web and mobile app development. Ionic has done a significant amount of work in mobile development. Similar to React, Angular can also be used for both single- and multiple-page web apps. Angular also has an additional mobile development framework, which is NativeScript.

Hence, it’s tough to choose a real winner between React vs. Angular, and we will call it a draw situation.

14. Toolset:

React

React uses multiple code editors like Sublime Text, Atom, and Visual Studio. It uses the Create React App (CLI) tool for bootstrapping a project, while the server-side rendering is done with Next.js framework. For testing the app written in React, calls for multiple tools for different elements. 

Angular

Angular, like React, also uses different code editing tools like Sublime Text, Aptana, and Visual Studio. The project is set up using Angular CLI, while the server-side rendering is done through Angular Universal. 

The Angular IO testing and debugging for a complete project are possible with a single tool like Jasmine, Protractor and Karma. But, this is not possible in the case of React js app development. A set of tools is required for performing different sets of testing.

For example, you will require Jest JavaScript code testing, Enzyme and Unexpected-React for component testing, Skin-deep for Render testing utils, React-unit for unit testing, and so on. This increases the efforts and time required in the testing process.

But the point of difference between Angular and React technology is that Angular can be tested entirely with only one tool. It can be either Karma, Protractor, or Jasmine. It is also one of the unique Angular advantages over React. So, the winner of this React vs. AngularJS war is Angular.

15. Community:

React

In React vs. Angular, React is one of the most popular JS frameworks globally, and there is a large community of developers developing it and using it for app development. Working with React, you have to be an active learner since the framework is continuously evolving, and new updates are being released.  

Keeping pace with all the changes is sometimes difficult, even when the community moves forward with the latest documentation. The community support on thematic forums helps in solving the issue of lack of documentation. 

Angular

Angular, on the other hand, has less community support than React. It faces a lot of cynicism, partially due to the low popularity of Angular 1.0. Due to its steep learning curve, developers used to dismiss the framework as a complex framework. What works in building Angular’s reliability is that the framework has been developed by Google. 

Google acts as a godfather and provides all-time support to the framework and reiterates it. Documentation often falls behind because of its continuous updates.

GitHub is the most popular community network by developers, coders and React has much broader community support than Angular on GitHub and GitLab. This upholds React at a slightly higher position than Angular when it comes to community support.

To wrap it up, it’s quite clear from the benefits point of view, in the React vs. Angular war, React has won by more no. of votes. Higher community support, more popular, customizable, flexible, more comfortable to learn, and to top faster development cycle makes React a preferred framework for app development. 

React vs. Angular: The Brand Game

The post What is better React or Angular for App Development? appeared first on EngineerBabu Blog.

First of all, people generally confuse whether Angular is a framework or library? Well, Angular is an open-source JavaScript framework by Google. It was launched in 2009, initially known as Angular.js, but after the release of Angular 2.0 in October 2014 .js extension is replaced by its versions. The latest version of Angular is Angular 9.

In recent times, Angular is booming in the industry, with 504,884 websites built in it. The graph below better explains the current scenario of Angular.

10 Reasons to choose Angular for Website Designing

Looking at its high marketability pace in this era of technological advancement, I have listed some worthy reasons why you should choose AngularJS for your next front end project:

1. Scalability: AngularJS framework provides high scalability. It gives the moderate capacity to change or resize module, components, logical view, etc. at any stage of development. Thus, it can extend existing logic and writing new features based on a tricky foundation with maintaining the unidirectional flow.

2. Framework vs. Library: When it comes to front end development, Angular is generally compared with React.js, but there is a massive difference between them. Angular is a framework whereas, React.js is a JavaScript library. React takes longer to set up than Angular. Angular lets you create projects and build apps relatively quickly. Plus, you get to add new features with AngularJS through its self libraries, unlike React.js.

3. Community Support: It is built and maintained by Google. Conferences devoted to AngularJS are holding worldwide; it is discussed at hackathons and in various IT communities. There are many book sand online supports available for AngularJS developers. For the enterprises’ owner, choosing AngularJS for their web development not only becomes trendy but also makes them easier to find the perfect Angular developer.

4. Speed: Thus, AngularJS is a framework, not a library; the code is precise. It lets developers write minimum code as compared to simple HTML, CSS, and JavaScript. It makes the code more lightweight, as well as easier to read and support since instead of describing all the steps needed to achieve something, we describe only the necessary result.

In JavaScript

< !DOCTYPE html >
< html >
< head >
< title >Demo App< /title >
< /head >
< body >
< table id="employees" border="1" >
< tr >
< th >Name< /th >
< th >Designation< /th >
< /tr >
< /table >
< script type="text/javascript" >
var employees = [
{name: 'Ankit Vadi', designation: 'Sr. Software Engineer'},
{name: 'Uzaif Nilger', designation: 'Sr. Software Engineer'},
{name: 'Gautam Moradiya', designation: 'Sr. Software Engineer'},
{name: 'Pratik Panchal', designation: 'DevOps'},
{name: 'Harshil Sanghavi', designation: 'Sr. Business Development Manager'}
];
var employeeList = document.getElementById('employees');
employees.forEach(function(employee){
var employeeDetail = document.createElement('tr'),
employeeName = document.createElement('td'),
employeeDesignation = document.createElement('td');
employeeName.innerHTML = employee.name;
employeeDesignation.innerHTML = employee.designation;
employeeDetail.appendChild(employeeName);
employeeDetail.appendChild(employeeDesignation);
employeeList.appendChild(employeeDetail);
});
< /script >
< /body >
< /html >

In AngularJS

< !doctype html >
< html >
  < head >
    < title >My AngularJS App< /title >
    < script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js">< /script >
  < /head >
  < body ng-app="EmployeeApp" >
    < table border="1" ng-controller="employeesController as empCtrl" >
      < tr >
        < th >Name< /th >
        < th >Designation< /th >
      < /tr >
      < tr ng-repeat="employee in empCtrl.employees" >
        < td >{{ employee.name }}< /td >
        < td >{{ employee.designation }}< /td >
      < /tr >
    < /table >
  < /body >
  < script type="text/javascript" >
    employeeApp = angular.module('EmployeeApp', []);
    employeeApp.controller('employeesController', function() {
      this.employees = [
        {name: 'Ankit Vadi', designation: 'Sr. Software Engineer'},
        {name: 'Uzaif Nilger', designation: 'Sr. Software Engineer'},
        {name: 'Gautam Moradiya', designation: 'Sr. Software Engineer'},
        {name: 'Pratik Panchal', designation: 'DevOps'},
        {name: 'Harshil Sanghavi', designation: 'Sr. Business Development Manager'}
      ];
    });

5. PWA: PWA stands for -Progressive Web Application. The web applications built with AngularJS that make them behave like native apps. The Built-in Application Angular behaves like a cross-platform, which can runs on both Android and iOS with the help of Angular CLI. It is highly used by service workers to implement Android and iOS hybrid apps.

6. Lazy Loading: Lazy loading technique in Angular allows you to load JavaScript components asynchronously when a specific route is activated. No other unnecessary pages or route is called while using with AngularJS as front end development. The app will load the ‘AppComponent’ by default at the root URL, then when the user navigates to lazy/load-me, the lazy module will be loaded asynchronously.

7. MVC Architecture: Model View Controller -Models are responsible for maintaining all the data. The View aims to display the essential data, whereas the Controller aims to bridge the gap between View and Model MVC splits the entire application into different components, which allows creating single-page applications.

8. Dependency Injection: Dependency Injection (DI) is a vital application design pattern. The whole of AngularJS has a built-in dependency injection subsystem to ease the development process.

9. Testing simplicity: Due to several distributed parts, testing became uncomplicated. Separation of modules enables the users to load only the required services and perform automatic testing smoothly.

10. Cost-Effective: Last but not least, the primary reason to choose AngularJS is that it is cost-effective. It is an open-source framework and has massive, and support is available in the market. Hire a dedicated Angular developer now.
