What is JSX?
A syntax extension that looks like HTML but compiles to React.createElement calls. It allows expressions inside braces, requires a single root (or a fragment), and uses className/htmlFor instead of HTML attribute names.
Example
const el = <h1 className="title">{2 + 3}</h1>;
// compiles to React.createElement('h1', { className: 'title' }, 5)
