Explain React concept: JSX.

Summary

JSX is a JavaScript syntax extension that describes React elements with XML-like markup.

Longer Answer

JSX is compiled to JavaScript calls that create React elements. It lets UI structure live close to the logic that produces it, while still using JavaScript expressions for values, conditions, lists, and event handlers.

In interviews, stress that JSX is not HTML. Attributes use React naming such as className and htmlFor, expressions go inside braces, and components must return one renderable tree, often with fragments when no wrapper element is needed.
