Getting Started with React

React is a powerful JavaScript library for building user interfaces. In this guide, we'll cover the fundamentals you need to know to start building modern web applications.

## What is React?

React 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.

## Key Concepts

### Components Components are the building blocks of any React application. They let you split the UI into independent, reusable pieces.

### JSX JSX is a syntax extension to JavaScript that lets you write HTML-like code in your JavaScript files.

### Props Props are arguments passed into React components, similar to function parameters.

### State State allows React components to create and manage their own data.
