1. React Basics
These are the non‑negotiables — the foundation of everything else.

Components — the building blocks of React

JSX — HTML inside JavaScript

Props — passing data into components

State — storing and updating data

Events — handling clicks, inputs, forms

Conditional Rendering — show/hide UI

Lists & Keys — rendering arrays

Once you understand these, you can build simple apps.

2. React Hooks
Hooks are the heart of modern React.

useState — manage component state

useEffect — run code on load, update, cleanup

useRef — store values without re-render

useContext — global state without Redux

These unlock real interactivity.

3. React Project Structure
Learn how a real project is organized:

src/components/

src/pages/

src/hooks/

src/services/

src/context/

This is what makes your code scalable.

4. React Routing
For multi‑page apps:

Navigation

Protected routes

Dynamic routes

Layout components

Every real app uses routing.

5. API Integration
Learn how to connect React to a backend:

fetch()

axios

GET / POST / PUT / DELETE

Handling loading & errors

This is where your React app becomes useful.

6. State Management
When your app grows, you need global state:

Context API

Redux Toolkit

Zustand (lightweight alternative)

Startups often use Context or Zustand because they’re simple.

7. React UI Styling
Choose one styling approach:

CSS Modules

Tailwind CSS

Styled Components

Material UI

Tailwind is the fastest for startups.

8. Authentication
You’ll need this for login systems:

JWT

Protected routes

Storing tokens

Role-based access

This ties directly into the login system you’re building.

9. React Best Practices
Learn how to write clean, scalable code:

Component reusability

Folder structure

Avoiding prop drilling

Using custom hooks

Performance optimization
