📘 Day 20 — Avoiding Prop Drilling: Techniques & Patterns

📘 Day 20 — Avoiding Prop Drilling: Techniques & Patterns

Prop drilling occurs when data is passed through many layers of components unnecessarily. React offers several solutions to avoid this.

🔹 1. Use Context API

Great for global data such as themes, user info, or language.

🔸 2. Use Custom Hooks

function useUser() {
  const [user, setUser] = useState({ name: "Rahul" });
  return { user, setUser };
}

function Profile() {
  const { user } = useUser();
  return <p>Welcome, {user.name}</p>;
}

💡 3. Use State Management Libraries

  • Redux Toolkit
  • Zustand
  • Recoil

These libraries help manage complex state without excessive prop passing.
