React JSX

JSX is a syntax extension for JavaScript that allows developers to write HTML-like code directly within their JavaScript files when building React components.

How JSX Works

Under the hood, JSX is compiled into regular JavaScript function calls that create React elements, which are then rendered to the DOM.

JSX Expressions

JSX allows embedding JavaScript expressions inside curly braces, making it easy to render dynamic values, conditionals, and lists within markup.

Best Practices

Keeping JSX readable by breaking large components into smaller ones and avoiding overly complex logic inside the markup leads to more maintainable code.
