Introduction
React is a popular web development JavaScript library. Different names for ReactJS include React.js, ReactJS, and React. Today, many large-scale organizations use React JS (Netflix, Instagram, to mention a few). There are numerous advantages to utilizing this framework over other frameworks, and it has consistently ranked among the top 10 programming languages in multiple language ranking indexes over the last few years.

What is React JS?
Facebook created the React.js front-end JavaScript framework. We utilize React to create composable user interfaces with declarative code that is predictable and efficient. It’s an open-source, component-based framework that’s in charge of building the app’s view layer.
- The Model View Controller (MVC) architecture is used by ReactJS, and the view layer is in charge of handling mobile and web apps.
- React is well-known for creating single-page apps and mobile apps.
Features of React JS
JavaScript Syntax Extension (JSX)
For many web developers, JSX is the preferred language. Although JSX is not required for React development, there is a significant difference between authoring react.js documents in JSX and JavaScript. JSX is a JavaScript syntactic extension. Using this method, we can write HTML structures in the same file as JavaScript code.
Unidirectional Data Flow and Flux
React.js is designed to only support data that is traveling in one direction, downwards. Additional features will be required if the data must travel in a different direction.
React includes a collection of immutable data points that are provided to the component renderer as HTML tag properties. The components cannot directly edit any properties, but they do support a callback method for doing so.
Virtual Document Object Model (VDOM)
In React, a virtual DOM is a memory-based, lightweight duplicate of the real DOM. Real DOM manipulation is substantially slower than VDOM manipulation because nothing is drawn on the screen. When an object’s state changes, VDOM updates only that object in the real DOM instead of the complete object.
When compared to alternative front-end technologies, which must update each item even if only a single object in the web application changes, this allows things to move quickly.
Debugging
Due to the large community’s assistance, testing React apps is simple. Even Facebook has a little browser extension that makes debugging React much easier and faster.
Let’s have a look at some key ReactJS principles next.
