Overview
Developed by Meta (formerly Facebook), React revolutionized web development with its declarative approach and the 'Virtual DOM.' It allows developers to build complex UIs from small, isolated pieces of code called components.
Key Concepts
- Components: Reusable UI building blocks.
- JSX: A syntax extension that allows writing HTML-like code within JavaScript.
- Hooks: Functions that allow using state and other React features in functional components (e.g.,
useState,useEffect). - Virtual DOM: A lightweight representation of the real DOM used to optimize updates.
Ecosystem
React has a massive ecosystem, including Next.js, Remix, and React Native for mobile development.
