Whilst talking about Javascript and its popularity, million of users around the world will not miss out on the discussion on React and Angular. The difference between React and Angular can be scrolled on the web and you will be able to find discussions and debates deeply contrasting ideas about them. Here are a few more points related to React vs. Angular. Let us discuss.

What is ReactJS ?

ReactJS is maintained by Facebook, React.js is an open-source JavaScript library for creating desktop, web, and mobile application UIs. In contrast to most of the websites, those who worked with React don't have server-side rendering, they are rendered in the browser. This implies users don't need to wait for the server response to render another page. It's a quicker experience, which is particularly significant for mobile applications. React's tool library permits developers to fabricate components that are dropped onto a website page. These components, which resemble custom HTML components, are what the clients see on the site. Components can be reused across applications and are a lot simpler to refresh and update than looking through lines of code. Organizations that use React incorporate Facebook (and Instagram), Uber, and Netflix, among others.

Benefits of ReactJS Version
Let us have a quick glance at why should you use React?
  • Straightforwardness React is easy to learn and apply on account of its-
  • dependence on JavaScript,
  • the simplicity of blending in with HTML,
  • component-based architecture.
Any developer with an essential comprehension of JavaScript would have the option to get acquainted with React and begin making exceptionally responsive applications very quickly.
  • Efficiency In JavaScript, reusable code is extricated to a function or class. In React, it can be well-written as a component. By incorporating reusable components, and thusly helping limit the violations of the DRY principle, React speeds up development and makes it more efficient.
  • Quick rendering React's Virtual DOM accomplishes high application performance and satisfying user experience while making your developer’s work quicker.
  • Community support There's an abundance of assets and tutorials for React accessible on the web, just as an active community ready to get you out of the issues.
What is AngularJS?

Angular is an all-in-one open-source JavaScript framework that is maintained by Google, to manufacture profoundly responsive single-page applications. Similar to ReactJS, an Angular-based website will see all site changes made in the program. Instead of interacting with a server to stack data, a browser-side experience allows the page to render rapidly with a more mobile-like experience. Angular recently observed the release of its most current version of Angular 9, which is built-on TypeScript, a superset of JavaScript.

Since React is a JavaScript library instead of the full JavaScript framework of Angular, many developers will include more libraries when utilizing React to give it the usefulness of a total framework.

Benefits of AngularJS
Now, let us have a quick glance at why you should use Angular?
  • Clear and brief code Angular’s basic component architecture dispenses with the requirement for unnecessary code and makes development smooth. Being built with TypeScript implies that the framework assists developers with finding and eliminates error at an early stage in the development procedure.
  • Consistency Independent logical and functional components are the building blocks of Angular. They are reusable, firm LEGO-like blocks of code that can be utilized to rapidly scale new and existing applications. In addition, the autonomy of every part makes it simple for developers to test an application for errors.
  • Documentation and community support On the authority Angular site, there is a lot of documentation that developers can depend on as they get acquainted with the system or experience issues while coding. The website is likewise a decent place to get up to date on any news or updates. Angular, much the same as React, additionally appreciates active community support, including conversation sheets on stages, for example, Gitter, Stack Overflow, Facebook, and Reddit.
  • Simple testing Angular utilizes Jasmine with the Karma test runner and offers a testing library (TestBed) that permits developers to effectively unit test their components. Furthermore, it accompanies Protractor arranged for simple e2e testing.
React vs. Angular – History
React, launched by Facebook, in 2013. React is mostly used by the Facebook company in its products like Facebook, Instagram, and Whatsapp. In November 2018, Facebook released the latest version, 16.X.
Angular, introduced by Google, released in 2010. Angular is a Typescript-based javascript framework. The next version Angular 2 (dropped the JS from the name- AngularJS), Angular 2+. The latest version is Angular 10, released in June 2020.

React vs Angular – Popularity

The explanation behind the developers why they like React or Angular is that since React includes more Javascript and having an alternate syntax JSX (Javascript XML), it has a stricter setup, architecture, and environment of React. Thus, developers utilize Angular more for this situation. Angular is a well-structured technology with an immense amount of projects and assets.

React vs. Angular – Comparison of Component Model

React exhibits entirely different characteristics. It combines the UI parts and behavior of components. Here is the component model of React:

import React from 'react';
             import 'ExampleComponent.css';
             export default class ExampleComponent extends React.Component {  
                 constructor(props) {    
                      this.state = { message: 'Hello from component!' };  
                  render() {    
                      return (
                         <div className="container">
In Angular, components known by the name of directives. Angular separates the UI components, as components are in HTML tags and their behavior in Javascript code.  So, it helps in faster angular development services. Here is the component model of Angular:

import { Component } from 'angular2/core';


   selector: 'component-placeholder',

   templateUrl: 'app/example.template.html',

   styleUrls: [ 'app/example.css' ]


export class ExampleComponent {

   public message = 'Hello from component!';

React vs. Angular – Size and Load time
The size of libraries in Angular and React are:
Angular: Depends on Bundle Size
React: 116KB
React vs. Angular – Learning Scale
Difficult- Angular has a steep learning curve since learning includes mastering in MVC and Typescript, so it takes time to learn the complete Angular.
Moderate- React comes with the starting guide, making it easier to start with the react development. But, it does not mean you would not face difficulties learning about the libraries and integrations in React.

Factors to consider before choosing a react angular framework
  1. Learning Curve of the Technology
  2. Benefits on the Server-Side and User-Side Aspects
  3. Functionalities, Special Features, and Components
  4. Updates, Trends, and Popularity on the Web Development Industry
Though React and Angular both are closely equal based upon the popularity among their users. Both of the frameworks have Javascript component-based architecture. Here is a short summary of the primary differences between ReactJS and AngularJS-
Javascript, HTML, JSX
ReactNative for mobile version (Android, iOS)
Relatively small (116 kb)
Released Year
Data Binding
App Size
UI Rendering
Github Rating
Learning Curve
2010 (Angular JS)
2016 (Angular2+)
Javascript, Typescript
NativeScript (Web, iOS, Android)
Depends upon bundle size
It is undeniable that Angular is used for building applications for its readability, reusability, and scalability at a large scale. Angular is most popular among Javascript developers but React is easy to learn because of the multiple integrations of some mandatory tools and libraries to manage dependency.
Final Words On reacting js vs angular js
Angular and React are both developing and being embraced by the large players on the tech scene. One is a steady, very much characterized, and normalized system that is incredible for long-term projects, while the other is a library that can be utilized to gather a model with reusable components surprisingly fast. Passing a subjective judgment on which one is "better" without becoming more acquainted with React and Angular's unique qualities and shortcomings would be unhelpful and misleading. Your choice on which one to go with ought to eventually rely upon:
  • the points of interest of your venture
  • the current range of abilities of your engineers
  • your financial plan
