React.jsFrontend
A powerful JavaScript library for building interactive user interfaces with component-based architecture.
Overview
React.js is a declarative, efficient, and flexible JavaScript library for building user interfaces. It lets you compose complex UIs from small and isolated pieces of code called components. React makes it painless to create interactive UIs with predictable state management.
Getting started
Prerequisites
Before getting started with React.js, ensure you have basic knowledge of frontend development.
To get started with React, you'll need Node.js installed on your system. The easiest way to begin is by using Create React App, which sets up a modern React development environment with zero configuration. You can create a new React app by running 'npx create-react-app my-app' in your terminal.
