What is difference between React and ReactJS.

In practice, there is no difference between React and ReactJS—they refer to the same technology. Both terms refer to the same library/framework for building user interfaces in JavaScript. React and ReactJS are often used interchangeably, with React being the more popular term.

This can easily cause confusion, especially for beginners, but here is the good news: they all are the same thing. There is no difference between React and React JS, as they are two names for the same JavaScript library developed by Facebook and used to build user interfaces.

React is a framework that employs Webpack to automatically compile React, JSX, and ES6 code while handling CSS file prefixes. React is a JavaScript-based UI development library. Although React is a library rather than a language, it is widely used in web development.
