JSX is a syntax extension for ReactJS that adds support for writing HTML tags in JavaScript. On top of ReactJS, it creates a very powerful way to express a web application. If you're familiar with ReactJS, you know that it's a library for implementing web component-based frontend applications..
Simply so, why JSX is used in react?
JSX allows us to write HTML elements in JavaScript and place them in the DOM without any createElement() and/or appendChild() methods. JSX converts HTML tags into react elements. You are not required to use JSX, but JSX makes it easier to write React applications.
Beside above, should React files be JS or JSX? So you are forced to use JS files instead of JSX. And since react is just a library for javascript, it makes no difference for you to choose between JSX or JS. They're completely interchangeable! Hence all React files that contain them are JSX and not JS.
