React v/s Angularjs, both are  advanced, widely adopted JavaScript (JS) technologies that we use to create interactive single-page applications (SPAs). Use of JS tools for fast single-page application development is constantly growing, making the choice of which technology to rely on more challenging for us as web developers.

React v/s Angularjs

React v/s Angularjs

Both React and AngularJS are currently used by many businesses, news, and travel companies in the USA, UK, Canada, France, Germany, Australia, and other countries.

This Model–View–Controller framework has become extremely popular among web developers.

React vs Angular Comparison :

The main differences between AngularJS (the framework) and React (the library) are in the following aspects: Componentization, Data binding, Performance, etc

Let’s look at the aspects of both :

AngularJS has a very complex and fixed structure because it's based on the three layers — Model, View, and Controller.

An object $scope in AngularJS is responsible for the Model part, which is initialized by the Controller and then transformed into HTML to create the View for the user. AngularJS provides many standard services, factories, controllers, directives, and other components that will take some time for a JavaScript developer to master initially.

React is a large JavaScript library that helps us update the View for the user. But React still doesn't let us create applications on its own. The library lacks the model and controller layers. To fill in the gap, Facebook introduced Flux, which has numerous variants nowadays, to control the application workflow.

var TodoApp = React.createClass({
getInitialState: function () {

nowShowing: app.ALL_TODOS,
editing: null,
newTodo: ''
handleChange: function (event) {

Data Binding :

AngularJS connects the Document Object Model (DOM) values to Model data through the Controller using two-way data binding. In short, if the user interacts with a field and provides a new value to the app, then not only the View is updated, but the Model as well.

Two-way data binding is beneficial for AngularJS as it helps us write less boilerplate code to create interactions between components (the View and the Model) in our application. We don't have to invent a method to track changes in the app and change our JavaScript code accordingly.

But what are the advantages of React over AngularJS with regards to data binding? React uses one-way data binding, meaning we are able to direct the flow of data only in one direction. Because of this, it’s always clear where the data was changed. It’s worth noting that two-way data binding was available in React before v15 thanks to ReactLink.

In order to implement unidirectional data flow in React, Facebook created its own application architecture called Flux. Flux controls the flow of data to React components through one control point – the dispatcher.


There are two things to take into consideration when we talk about Angular's performance. Angular 1.x and higher relies on two-way data binding. This concept is based on “dirty checking," a mechanism that can make our AngularJS application laggy.

The creators of React introduced the concept of the virtual Document Object Model, which is regarded as one of the greatest advantages of React in comparison with mature frameworks, including AngularJS.

Resolving Dependencies

AngularJS uses a basic Object Oriented Programming (OOP) pattern called dependency injection, meaning we write dependencies in a separate file. It’s inconvenient to create a dependency directly in an object. In AngularJS, dependency injection is inherent to any standard functions that we declare for an AngularJS factory or service.

The difference between React and AngularJS with regards to dependency injection is that React doesn’t offer any concept of a built-in container for dependency injection. But this doesn't mean we have to think of a method to inject dependencies in our React project. You can use several instruments to inject dependencies automatically in a React application.


Both have of it different Functionalities and unique behaviors. We cant choose them which is perfect. Developers use both of us according to their needs. As per website development significantly both are useful. Choose as your own which is best for you.
