what is jsx

JSX, which stands for JavaScript XML, is a syntax extension for JavaScript that allows the creation of DOM trees using an XML-like syntax. It was initially created by Facebook for use with React, but has since been adopted by multiple web frameworks. JSX makes it easier to write and add HTML in React, and it allows developers to write HTML directly within JavaScript code. JSX is essentially a syntactic sugar that is transpiled into nested JavaScript function calls structurally similar to the original JSX. It allows for the embedding of expressions inside curly braces, and it provides a range of element attributes designed to mirror those provided by HTML. JSX is generally transpiled into regular JavaScript at runtime, and it is processed during a software build process before the application is deployed. JSX is an embeddable XML-like syntax meant to be transformed into valid JavaScript, and it has seen implementations beyond React, with TypeScript supporting embedding, type checking, and compiling JSX directly to JavaScript).
