. It simplifies the process of building interactive user interfaces (UIs). Imagine a React UI as a collection of reusable components, each responsible for outputting a small, reusable piece of HTML code1. Here are some key points about React:
- Components: React applications are composed of reusable components. Each component represents a part of the UI, such as a navigation bar, footer, or main content area2.
- JSX Syntax: React uses JSX (JavaScript XML), an XML/HTML-like extension to JavaScript. JSX allows you to write UI elements in a familiar way, combining HTML-like tags, attributes, and JavaScript expressions3.
- Rendering: React elements are rendered using the
ReactDOM.render()method. Elements are immutable, meaning they cannot be changed directly; instead, you render a new element when needed3. - Babel: React relies on Babel, a JavaScript compiler that translates JSX into regular JavaScript. Babel allows you to use modern JavaScript features (ES6) in your React code3.
