Stay Ahead with the Power of Upskilling - Invest in Yourself! 
JSX is a syntax extension to JavaScript. We recommend using it with React to describe what the UI should look like. JSX may remind you of a template language, but it comes with the full power of JavaScript. JSX produces React “elements”.
JSX looks like a regular HTML in most cases. We already used it in the Environment Setup chapter. Look at the code from App.jsx where we are returning div.
App.jsx
import React from ‘react’;
class App extends React.Component {
render() {
return (
<div>
Hello World!!!
</div>
);
}
}
export default App;
Even though it’s similar to HTML, there are a couple of things we need to keep in mind when working with JSX.
