🧭 1. Core Prerequisites (Before React)

Make sure your fundamentals are solid:

✅ Web Foundations

HTML5 → semantic tags, forms, accessibility

CSS3 → flexbox, grid, transitions, responsive design

JavaScript (ES6+)

let/const, arrow functions

destructuring, spread/rest

template literals

promises, async/await

array methods (map, filter, reduce)

modules & imports

⚛️ 2. React Fundamentals

Start with core concepts and small projects.

📘 Topics:

What is React & why use it

Components (Functional Components)

Debouncing & cleanup

Custom hooks

🎯 Project Idea: Weather App or Movie Search App using public API.

🧭 6. React Router

Handle navigation and routes.

React Router v6+

Dynamic routes & params

Nested routes

Navigation (Link, NavLink)

Protected routes (Auth-based)

🎯 Project Idea: Multi-page Blog or Dashboard.

⚙️ 7. Performance Optimization

Make your React apps faster.

React.memo

useCallback, useMemo

🎯 Project Idea: Portfolio / Blog using Next.js.

🧠 11. TypeScript with React

Gradually add TypeScript for large projects.

Props & State typing

Custom hooks typing

Type-safe API responses

🎯 Project Idea: Rebuild one of your projects in TypeScript.
