Q: What exactly is JSX?

A: JSX is a syntax extension for JavaScript that lets you write markup inside a JavaScript file. It is a domain-specific language and template language that requires a compiler (like a source-to-source compiler) to convert the syntax into standard JavaScript that browsers can understand.

Q: Is JSX exclusive to React?

A: While JSX was created by Meta for use with React, it is not strictly exclusive to it. The syntax is also used by other frameworks and libraries, including Vue.js and SolidJS.

Q: Does the browser understand JSX directly?

A: No, browsers cannot read JSX natively. It is classified as "syntactic sugar," meaning it must be compiled or transpiled into regular JavaScript using a source-to-source compiler before execution.
