What is JSX in React and how does it work?

JSX stands for JavaScript XML. It's a syntax extension for JavaScript that looks similar to HTML. In React, JSX is used to describe what the UI should look like.

Why should I use JSX instead of plain JavaScript?

JSX makes it easier to write and visualize the structure of your UI components. It allows you to write HTML-like syntax directly in your JavaScript code, which can improve readability and maintainability.

Can I use JSX without React?

JSX is primarily designed for use with React, but you can use it with other libraries or frameworks that support it. However, you would need a compiler like Babel to transform JSX into regular JavaScript.

What are some common mistakes when using JSX?

Common mistakes include not closing tags properly, using JavaScript expressions without curly braces, and forgetting to return a single parent element from a component.
