🧭 React Beginner Roadmap (2025 Edition)

---

🟢 1. Prerequisites (Before React)

Make sure you're confident in:

✅ HTML & CSS

• Semantic HTML
• Flexbox & Grid
• Forms
• Media Queries

✅ JavaScript (ES6+)

• let, const, arrow functions
• map, filter, reduce
• Spread/rest operators
• Destructuring
• Callbacks, Promises, async/await
• this, closures, scope, hoisting
• DOM manipulation

✅ Git & GitHub

• Clone, commit, push, pull
• Creating branches
• README writing

---

🟡 2. React Core Concepts

🎯 Goal: Understand the core building blocks of React.

📦 Environment Setup

• Install Node.js & npm

• Create a project using:

  npx create-react-app my-app

  or use Vite for a faster setup:

  npm create vite@latest

📘 JSX (JavaScript XML)

• Embedding expressions
• Differences from HTML (e.g., className vs className)

🔥 Components

• Functional components
• Props
• Reusability

🔄 State Management (Local)

• useState hook
• Updating and rendering state

📢 Event Handling

• Handling user input
• Passing functions as props

🌐 Conditional Rendering

• if/else, ternary operator
• && short-circuit

🔁 Lists and Keys

• Rendering lists with .map()
• Importance of unique key

🎨 Styling in React

• CSS Modules
• Inline Styles
• Styled Components (optional)
• TailwindCSS (optional)

---

🔵 3. React Intermediate Concepts

🎯 Goal: Build apps that can manage UI logic better.

🪝 React Hooks (Core)

• useEffect for side effects (API calls, event listeners)
• useRef for accessing DOM or persisting values
• useContext for prop drilling avoidance

📡 Fetching Data

• Using fetch or axios
• Loading and error states

🧩 Forms and Controlled Components

• onChange, value in inputs
• Controlled vs Uncontrolled forms
• Form validation (optional: libraries like Formik/Yup)

🗂️ Component Reusability and Composition

• Children props
• Higher Order Components (HOC)
• Custom Hooks

---

🟠 4. React Routing & Navigation

🎯 Goal: Build multipage apps.

🧭 React Router DOM

• Installation:

  npm install react-router-dom

• Basic Routing: <BrowserRouter>, <Routes>, <Route>

• Route Parameters

• Navigation: useNavigate()

• Nested Routes

• 404 Pages

---

🔴 5. React Advanced Concepts

🎯 Goal: Create scalable and performant React apps.

📦 Global State Management

• Context API
• Redux Toolkit or Zustand (recommended)
• When to use global state?

💡 Code Splitting & Lazy Loading

• React.lazy, Suspense

🚀 Performance Optimization

• React.memo, useMemo, useCallback
• Virtualization (React Window)

🧪 Testing (Optional but Useful)

• Unit Testing with Jest
• Component Testing with React Testing Library

---
