Intro to React

React is a JavaScript library for building user interfaces. It makes it easy to create interactive UIs by using a component-based approach.

Why Use React?

• Reusable components save time and make code cleaner
• Virtual DOM makes updates faster
• Strong community and tons of tools

Your First React Component

Let's create a simple "Hello, World!" component:

import React from "react"

function HelloWorld() {
  return <h1>Hello, World!</h1>
}

export default HelloWorld

Setting Up a Project (with Vite)

# Create a new React project with Vite
npm create vite@latest my-app -- --template react

cd my-app
npm install
npm run dev

Core Concepts to Learn

• JSX: JavaScript + XML syntax
• Props: Passing data into components
• State: Managing local component data
