In this article, we will learn about React js & angular, along with discussing the significant distinction that differentiates Angular from React js.

React.js: React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It’s ‘V’ in MVC. ReactJS is an open-source, component-based front-end library responsible only for the view layer of the application. It is maintained by Facebook. React uses a declarative paradigm that makes it easier to reason about your application and aims to be both efficient and flexible. It designs simple views for each state in your application, and React will efficiently update and render just the right component when your data changes. The declarative view makes your code more predictable and easier to debug. 
Features of React js:

  • Scalability: It is reasonable for enormous scale applications because of its adaptable structure and scalability.
  • Rich JavaScript Library: Developers from everywhere throughout the world are placing in an exertion to include significantly more features.
  • Code Reusability: It enables the developers to reuse the code components of different levels while working on the project.

Example: This example demonstrates the simple React js syntax.


import React from 'react';
import ReactDOM from 'react-dom';
var name = "Learner";
var element = <h1>Hello, { name }.Welcome to GeeksforGeeks.</h1>;


Simple React js example

Angular: It is a popular open-source JavaScript framework created by Google for developing web applications. Front-end developers use frameworks like Angular or React for presenting and manipulating data efficiently. Updated Angular is much more efficient compared to the older version of Angular, especially, the core functionality was moved to different modules. That’s why it becomes so much fast and smooth compare to the older one. Newly added angular CLI. With that package, you can create a scaffolding for your Angular project. 
Features of Angular:

  • Accessibility: It provides easier access as it holds ARIA-enabled components.
  • Templates: Angular holds several templates to create UI views in a much faster manner by providing and suggesting some syntax.
  • Testing: The program here is broken into several chunks which makes it easier to test. Testing is performed by the protractor in this case.

Example: This example demonstrates the simple Angular program.



<hello name="{{ name }}"></hello>

import { Component } from '@angular/core';
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
export class AppComponent  {
  name = 'Geeks';



import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';
  imports:      [ BrowserModule, FormsModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ]
export class AppModule { }


Simple Angular example

Difference between React.js & Angular:

Though both react js and angular seems similar, but still there is significant contrast that differentiates both React.js and Angular, which is given below.




Used as

React.js is a JavaScript library. As it indicates react js updates only the virtual DOM is present and the data flow is always in a single direction.

Angular is a framework. Angular updates the Real DOM and the data flow is ensured in the architecture in both directions.


React.js is more simplified as it follows MVC ie., Model View Control. This like angular includes features such as navigation but this can be achieved only with certain libraries like Redux and Flux. Needs more configuration and integration.

The architecture of angular on the other hand is a bit complex as it follows MVVM models ie., Model View-ViewModel. This includes lots of tools and other features required for navigation, routing, and various other functionalities.


React.js holds JSX hence the usage of HTML codes and syntax is enabled. But this doesn’t make react js a subset of HTML. This is purely JavaScript-based.

Angular, on the other, is a mere subset of HTML.


React.js is preferred when the dynamic content needed is intensive. As react js holds more straightforward programming and since it is reliable many apps such as Instagram, Facebook, and Twitter still prefer to react js over angular.

Angular is platform-independent and hence is compatible to work in any platform. Hence, the HTML app which is compatible with all the browsers can prefer angular. One major app which uses angular is YouTube.


React.js written in JavaScript.

Written in Microsoft’s Typescript language, which is a superset of ECMAScript 6 (ES6).

Dependency Injection

React.js Does not use the Dependency Injection concept.

Angular Hierarchical Dependency Injection system used.

Note: Angular is a great framework it has many improvements in terms of ReactJS, it is good at bigger applications. If you are a beginner or have less coding practice also if you want stability for your project you can go with ReactJS.
