JSX (JavaScript XML) is a syntax extension for JavaScript that allows developers to write HTML-like code directly within JavaScript files.
JSX is one of the core features of React, enhancing the development experience by enabling a clear and concise way to describe the structure of user interfaces (UI).
Key features of JSX include embedding expressions, attributes, nested elements, and conditional rendering.
JSX provides a declarative syntax, integration with JavaScript, and an enhanced developer experience.
