🔑 Tips for Beginners Learning React.js:


1. Don’t Skip JavaScript Fundamentals
React is just JavaScript with superpowers. If you don’t understand:
ES6 features (arrow functions, spread/rest, destructuring)
Array methods (
map
,filter
,reduce
)this
, scope, promises, async/await
…then React will feel like black magic. Master JS first—it pays off.
2. Understand Components Properly
Everything in React is a component.
Start with functional components (forget class components for now).
Practice breaking UI into small reusable pieces.
Example: A button, a card, a navbar — all should be separate components.
3. Learn State & Props Before Anything Else
Props = inputs (data you pass into components).
State = internal memory (data the component remembers).
If you don’t get props/state, nothing else (hooks, Redux, context) will make sense.
4. Hooks Are Your Best Friends
useState
→ for managing values that changeuseEffect
→ for side effects (fetch data, timers, subscriptions)useContext
→ for avoiding prop drilling
👉 Learn these 3 hooks solidly before moving on to fancy stuff.
5. Hands-On Projects > Reading Docs All Day
Instead of just watching tutorials:
Build a Todo App (classic for state/props practice).
Build a Weather App (practice API calls with
fetch
).Build a Theme Switcher (practice
useContext
).
Projects force you to connect dots faster.
6. Learn JSX Syntax Well
Remember, JSX is not HTML. Some quick gotchas:
className
instead ofclass
onClick={handleClick}
instead ofonclick="..."
{}
for embedding JavaScript
7. Styling Matters
Don’t overcomplicate it at first:
Use plain CSS or inline styles.
Later explore Tailwind CSS or Styled Components.
8. Think in Terms of Data Flow
React is one-way data flow (parent → child).
If you want to send data back, you pass a function as a prop.
9. Use DevTools
Install React Developer Tools in Chrome/Firefox → inspect components, see props/state live. This speeds up debugging a lot.
10. Be Patient with Advanced Stuff
Don’t rush into:
❌ Redux, Recoil, Zustand
❌ Server-Side Rendering (Next.js)
❌ TypeScript with React
👉 Learn those after you’re comfortable with React basics.
⚡ My suggestion for you:
Spend 1 week revising JavaScript.
Spend 2–3 weeks building small React apps with
useState
&useEffect
.Then slowly explore context, routing, and state management.
