Learning React? Here’s the 80/20 of What Actually Matters.
(Because you don’t need to master every hook and edge-case to build real apps.)
Let’s cut through the noise.
React is powerful, but it can feel overwhelming fast.
Too many tutorials will drown you in useMemo, Context APIs, Redux, Suspense, and a hundred things that don’t matter (yet).
So here’s the 80/20:
The 20% of React that will give you 80% of the results, confidence, and project-building ability. 👇
1. Components
Understand how to break your UI into reusable pieces.
✅ Functional components
✅ JSX syntax
✅ Props: how to pass data down
✅ Component composition
If you can build with components, you’re already halfway there.
2. State Management with useState
Forget Redux (for now).
Most projects only need useState.
Learn to:
✅ Track form inputs
✅ Toggle UI elements
✅ Store basic dynamic values
State is what makes your app interactive.
3. useEffect (and Why It Runs Too Many Times 😅)
This hook is your best friend and worst enemy.
✅ Use it to fetch data
✅ React to changes in props or state
✅ Control when side effects run with the dependency array
You don’t need to master it, just learn how not to crash your app.
4. React Router
✅ Learn how to navigate between pages
✅ Handle dynamic routes (like /users/:id)
✅ Link components without full page reloads
This gives your app a real “website” feel, critical for portfolios and real-world projects.
5. Building & Deploying a Small Project
Pick a simple project (to-do list, blog, weather app) and FINISH it.
✅ Create components
✅ Manage state
✅ Fetch from an API
✅ Route between pages
✅ Deploy to Netlify or Vercel
Until you’ve shipped, you haven’t really learned it.
🚫 What You Can Ignore (for now):
❌ Redux
❌ useMemo / useCallback
❌ Custom hooks
❌ TypeScript (if you're still shaky on JS)
❌ Suspense / lazy loading
