React Best Practices in 2024

Hey everyone! 👋

I've been working with React for a few years now, and I wanted to share some best practices that have really helped me write cleaner, more maintainable code.

1. Use Functional Components with Hooks

Always prefer functional components over class components. They're simpler, easier to test, and hooks make state management way cleaner.

// Good ✅

function UserProfile({ userId }) {

const [user, setUser] = useState(null);

useEffect(() => {

fetchUser(userId).then(setUser);

}, [userId]);

return <div>{user?.name}</div>;

}

// Avoid ❌

class UserProfile extends Component {

// ... old class component code

}

2. Custom Hooks for Reusability

Extract logic into custom hooks. This makes your components way cleaner and the logic reusable.

3. Proper Key Props

Always use stable, unique keys for lists. Never use array indices if items can be reordered.
