angularjsHow do AngularJS and React differ in terms of usage and features?

AngularJS and React are two popular front-end JavaScript frameworks. Although they share some similarities, they have some key differences in terms of usage and features.

Usage AngularJS is a full-featured framework, which means that it provides a complete set of tools for developing a web application. React, on the other hand, is a library, which means it only provides the view layer of a web application.


  1. Data Binding: AngularJS uses two-way data binding, which means that when a model is changed, the view is updated automatically and vice versa. React, however, uses one-way data binding, which means that the view is updated only when the state of the component is changed.

  2. DOM Manipulation: AngularJS uses a real DOM (Document Object Model) which means it can update the DOM directly when the model changes. React, however, uses a virtual DOM, which means it creates a copy of the DOM and makes the changes to the copy first.

  3. Routing: AngularJS provides a built-in router module which can be used to handle navigation between different views in the application. React, on the other hand, does not provide a built-in router and it needs to be integrated with a third-party library.

Example code

// AngularJS
var app = angular.module('myApp', ['ngRoute']);
app.config(function($routeProvider) {
    .when('/', {
      templateUrl: 'views/home.html',
      controller: 'HomeController'
    .when('/about', {
      templateUrl: 'views/about.html',
      controller: 'AboutController'
      redirectTo: '/'

// React
import { BrowserRouter as Router, Route } from 'react-router-dom';

      <Route exact path="/" component={Home} />
      <Route path="/about" component={About} />
