What is React JS?

React js is a JavaScript library created by Facebook. It was first created by Jordan Walke, a software engineer working at Facebook. It was first deployed on Facebook’s newsfeed in 2011 and later on in 2012.

React is currently one of the most popular JavaScript libraries. It is used for handling the view layer for web and mobile apps. ReactJS allows us to create reusable UI components.

React allows developers to create large web applications which can change data without reloading the page. It is to be fast, scalable, and simple.

Why should we learn React JS?

  • React is easy to learn and easy to use. Anyone who comes from a JavaScript background can understand and start using React in a few days.
  • Instead of separating the markup and logic in separate files, React uses components for this purpose.
  • React views are typically rendered using components that contain additional components specified as custom HTML tags.
  • It uses Virtual DOM, which creates an in-memory data structure cache, enumerates the resulting differences, and then updates the browser’s displayed DOM efficiently.
  • ReactJS comes out as a stronger framework because of the ability to break down the complex UI and allow users to work on individual components.
  • React uses one-way data binding, and an application architecture called Flux controls the flow of data to components through one control point – the dispatcher.
  • Flux features actions that are sent through a central dispatcher to a store, and changes to the store are propagated back to the view. When used with React, this propagation is accomplished through component properties.
  • We can use Browserify, Require JS, and ECMAScript 6 modules, which we can use via Babel ReactJS-di to inject dependencies automatically.

How does React JS Work?

While building client-side apps, a team of Facebook developers realized that the DOM is slow. So, to make it faster, React implements a virtual DOM that is a DOM tree representation in Javascript.

So when it needs to read or write to the DOM, it will use the virtual representation of it. Then, the virtual DOM will try to find the most efficient way to update the browser’s DOM.

Unlike browser DOM elements, React elements are plain objects and are easy to create. React DOM takes care of updating the DOM to match the React elements.

This is because JavaScript is very fast, and it’s worth keeping a DOM tree in it to speed up its manipulation.

Advantages of React js

  • Using virtual DOM will improve the app’s performance since JavaScript virtual DOM is faster than the regular DOM.
  • React Can be used on the client and server-side and with other frameworks.
  • It makes it easier for us to create templates.
  • React uses a one-way data flow, so only changes to the data result in changes to the UI.
