What is JSX?
React uses JSX to define the layout and appearance of components. JSX, which stands for JavaScript XML, is a syntax extension for JavaScript that allows developers to write HTML-like code within JavaScript. It provides a way to describe the structure of UI components in a more familiar and expressive manner. JSX provides a more expressive syntax for defining UI components compared to traditional JavaScript or string concatenation. With JSX, developers can write HTML-like code directly within their JavaScript files, making it easier to visualize and understand the structure of the UI. JSX allows developers to embed JavaScript expressions within curly braces {} directly within the HTML-like markup. After that JSX can be statically analyzed by tools like Babel which is open-source JavaScript transcompiler that converts ECMAScript 2015+ (ES6+) code into backwards-compatible JavaScript code. And babel convert JSX into browser friendly language for web application.
