React Learning Roadmap
Week 1: React Fundamentals
Components — The building blocks of React:
function Welcome({ name }) {
return <h1>Hello, {name}!</h1>;
}
JSX — HTML-like syntax in JavaScript
Props — Passing data between components
Rendering — How React updates the UI
Week 2: State & Events
useState Hook — Managing component data:
const [count, setCount] = useState(0);
Event Handling — onClick, onChange, onSubmit
Conditional Rendering — Show/hide based on state
Lists & Keys — Rendering arrays of data
Week 3: Advanced Hooks
- useEffect — Side effects (API calls, timers)
- useContext — Global state without prop drilling
- useRef — DOM references
- Custom Hooks — Reusable logic
Week 4: Routing & Forms
- React Router — Multi-page navigation
- Form handling — Controlled components
- Validation — Input checking
- URL parameters — Dynamic routes
Week 5-6: State Management & API

Common Mistakes Beginners Make
- Not learning JavaScript first — React IS JavaScript. Master JS basics first.
- Overusing state — Not everything needs useState
- Ignoring component structure — Plan your component tree
- Not using keys in lists — Causes rendering bugs
- Mutating state directly — Always use setter functions
