React Tutorial

Project: React-Tutorial

Purpose: This repository is a hands-on tutorial project to learn core React concepts by building small, focused examples and a progressive single-page application (SPA). It's designed for beginners who know basic HTML, CSS, and JavaScript (ES6+), and for intermediate developers who want a structured path to strengthen React fundamentals.

---

What you'll learn

• React component model (functional components and hooks)
• JSX and props
• State management with useState and useReducer
• Side effects with useEffect
• Component composition and lifting state
• Routing with react-router (basic usage)
• Fetching data and handling async requests
• Simple form handling and validation
• Styling approaches (CSS Modules / styled-components / Tailwind basics)
• Project organization and best practices

---

Prerequisites

• Node.js (v14 or later recommended) and npm or yarn
• Basic knowledge of JavaScript (let/const, arrow functions, promises)
• Familiarity with the command line

---

Getting started (local)

1. Clone the repository:

git clone https://github.com/your-username/react-tutorial.git
cd react-tutorial

2. Install dependencies:

npm install
# or
yarn install

3. Start the development server:

npm start
# or
yarn start

The app will open at http://localhost:3000 by default.

Available scripts

• npm start — run the dev server with hot reloading
• npm run build — build the production bundle into /build
• npm test — run tests (if included)
• npm run lint — run linters (optional)
