Context + Reducer: Simple State Containers
Combine Context + useReducer to build a tiny state container: Provider exposes state and dispatch via a custom hook.
Why Context + Reducer?
Goal: Package state logic into a Provider (Context) + reducer. Children read via a small custom hook: no prop drilling, predictable updates.
Design steps
Pattern:
- Create Context
- Inside Provider: useReducer(state, action)
- Provide {state, dispatch}
- Make useCounter()-style hook that calls useContext
