React Features

React Features
ReactJS is rapidly growing in popularity as the best JavaScript framework among web developers today. It plays an important role in the frontend ecosystem. Key features of ReactJS are:

• JSX
• Components
• One-Way Data Binding
• Virtual DOM
• Simplicity
• Performance

JSX
JSX stands for JavaScript XML. This is a JavaScript syntax extension. This is the XML or HTML-like syntax used in ReactJS. This syntax is handled by React Framework JavaScript calls. Extend ES6 to allow HTML-like text to coexist with JavaScript response codes. You don't have to use JSX, but I recommend using it with ReactJS.

Components
ReactJS is all about components. A ReactJS application consists of multiple components, each with its own logic and controls. These components are reusable, which helps you maintain your code when working on large projects.

One-Way Data Binding
ReactJS is designed to follow one-way data flow or one-way data binding. The advantage of one-way data binding gives you more control over your application. Additional functions are needed if the data flow goes in another direction
It is because components are supposed to be immutable and the data within them cannot be changed. Flux is a pattern that helps to keep your data unidirectional. This makes the application more flexible that leads to increase efficiency.

Virtual DOM
A virtual DOM object is a representation of the original DOM object. It works like a one-way data binding. The entire user interface is re-rendered in a virtual DOM representation whenever a change is made to the web application. Then check the difference between the old DOM representation and the new DOM. Once this is done, the actual DOM only updates what actually changed. This will make your application faster and avoid wasting memory.

Simplicity
ReactJS uses JSX files, which makes applications simpler and easier to code and understand. We know that ReactJS is a component-based approach which makes the code reusable as your need. This makes it simple to use and learn.

Performance
ReactJS is known to be a great performer. This feature makes it much better than other frameworks out there today. The reason behind this is that it manages a virtual DOM
