⭐ EASY WAY TO REMEMBER

If your state is	Use
Simple & used in 2–3 components	useContext
Complex but inside one component	useReducer
Shared across whole app, API, caching	Redux Toolkit

🧠 🔥 FINAL CLEAR DIFFERENCE (VERY IMPORTANT) 🔸 useContext ➡ Only shares state ➡ Does NOT manage complicated state ➡ Good for small apps

🔸 useReducer ➡ Manages complex logic inside a component ➡ Does NOT solve global state

🔸 Redux Toolkit ➡ Best global state solution ➡ Solves everything: loading, API, caching, error, store, slices ➡ Used in real-world professional apps
