Difference Between ReactJs vs AngularJs

React is a library that deals in view; on the other side Angular are a legit framework. ReactJs is used as a base for a single webpage or mobile application. It deals with the view layer of an application. AngularJS is an open-source javascript-based front-end web application framework. Its basic features are MVC, Data Model Binding, Writing less code, and Unit testing. But there is one similarity also both ReactJs vs AngularJs frameworks are very easy to use and build the high-end mobile or web application.

ReactJs

React is a Javascript library that is used for building user interfaces. It is maintained by Facebook and an individual group of developers. It is used for creating reusable UI components. I also help the developer to build a large application in which data can be changed without refreshing it. The main advantage of React Js is it is fast, scalable, and simple.

Advantage of ReactJs

SEO-friendly: ReactJs is very comfortable with SEO. You can easily run your ReactJs with the servers while other Javascript doesn’t support SEO.
JSX: In ReactJs for templating we use JSX. JSX is a simple JavaScript that allows HTML syntax and other HTML tags in the code. HTML syntax is processed into javascript calls of React framework.
React Native: It contains a native library that supports Native iOS, Android applications.
Simplicity: It is very simple to grab. Its component-based approach and well-defined lifecycle are very simple to use.
Easy to learn: Anyone with a basic knowledge of programming can easily ReactJs. For Learning ReactJs, you just need to know the basics of HTML and CSS.
Data-Binding: ReactJs use one-way data binding, and application architecture controls the flow of data via a dispatcher.
Testability: A reactjs application is very easy to test. Its views are very easy to configure and can be treated as an application.

AngularJs

AngularJS is an open-source javascript-based front-end web application framework that Google maintains. Its main component is the MVC (Model View Controller). AngularJs has addressed many problems that were coming at the time of single web page development.

Advantages of AngularJS

MVC(Model View Controller): The AngularJs framework is inbuilt on the famous concept of Model-View-Controller because of that code can be managed more easily.
Data-Binding: In this, there is no need to write code to bind data with the HTML controls. In Angular, it can be done by the snippets of code. It supports two-way data binding.
Less code: In Angular Js, you have to write a very little amount of code for Dom manipulation.
Unit Testing: It contains the testing framework name Karma, which helps design test cases of AngularJs application.
Routing: In AngularJs, routing is very easy. Routing means moving from one view to another view.

Conclusion

Both ReactJs or AngularJs is a very powerful and diverse approach for a front-end web application. It supports all small, medium and large enterprise applications. On one side, the ReactJs application SEO friendly, simple and easy to understand. On the other side, Angular Js applications are easy to develop and support a different form of testing.
