Why Learn React ?

React js Online Training

React offers great solutions to developers for front-end programming’s most persistent issues and allows them to build dynamic and interactive web apps with ease. It is an open-source JavaScript library designed by Facebook for creating rich and engaging web applications with speed, efficiency, and minimal coding.

React focuses on individual components that mean, instead of working on the entire web application, it allows a developer to break down the complex UI into simpler components. Even today, seven years past its release React is still one of the most used JavaScript frameworks and is growing rapidly in its path. It is fast, scalable, flexible, powerful, and has a robust developer community that’s rapidly growing.

React

React is a free and open-source front-end JavaScript library that is used for building interactive UIs and web applications. Its efficiency and flexibility let you compose complex UIs from small and isolated pieces of code called “components”.

Being in one of the most famous JavaScript UI libraries React for sure has millions of downloads every month. The best part is its features- it is complex, efficient, user-friendly, and fast. React is and will stay an in-demand skill in web development. Once you master React, you can become a much sought-after developer.

Once you have mastered React, you can learn:

   Node.js

   MongoDB

React Installation

Here are 4 easy ways to install React :

  Directly adding the React JavaScript file into the web page

  Using create-react-app

   With Codepen

  Using CodeSandbox

React Benefits
React is faster is due to its of its virtual DOM that renders everything in JavaScript and changes the things that are changed in actual DOM. Another feature that makes React work efficiently is the keys in Arrays through which React allows fast array changes in elements.
