What Is JSX in React, and why is it used?

JSX (JavaScript XML) is a syntax extension for JavaScript that allows developers to write HTML-like code inside JavaScript. It is used in React components to define UI structures in a readable and declarative way. JSX is compiled to JavaScript functions, making it more efficient and easy to use.

Using JSX improves code readability, maintainability, and performance by enabling component-based development with dynamic rendering.

Key Takeaways:

JSX allows writing HTML-like syntax inside JavaScript.
