What is React?

React is a JavaScript library for building user interfaces, created by Facebook in 2013. It's component-based and uses a virtual DOM for efficient updates.

Key Features

• Component-Based: Build encapsulated components that manage their own state
• Declarative: Design simple views for each state in your application
• Virtual DOM: React creates an in-memory representation of the actual DOM
• One-Way Data Flow: Data flows from parent to child components

Why Use React?

1. Reusable Components: Write once, use everywhere
2. Performance: Virtual DOM minimizes actual DOM manipulation
3. Large Ecosystem: Huge community and library support
4. Developer Tools: Excellent debugging tools available
