📌 1. Use useReducer for Complex State Logic

When managing nested or complex state, useReducer offers better structure than useState.

use_reducer
**Example:** ```js const [state, dispatch] = useReducer((state, action) => { switch (action.type) { case 'UPDATE_FORM': return { ...state, form: action.payload }; default: return state; } }, initialState); ```

🧠 2. Avoid Unnecessary Re-renders

Use React.memo to prevent re-renders of unchanged components.

react_memo
**Tip:** Wrap components with `React.memo` if they receive props that don't change frequently.

📈 3. Optimize Data Processing

Leverage useCallback and useMemo to memoize functions and results.

use_callback_memo
**Best Practice:** ```js const memoizedValue = useMemo(() => computeExpensiveValue(a, b), [a, b]); ```

📦 4. State Sharding Strategy

Split large state objects into smaller, focused slices for easier management.

🛠 5. Use Immutable Data Patterns

Always return new objects/arrays instead of mutating existing ones.

immutable_data
**Rule:** `const newState = { ...state, key: newValue };`

🧩 6. Selective State Updates

Update only the necessary parts of the state to minimize rendering overhead.

selective_updates
**Pro Tip:** Use `setState({ ...state, [key]: value })` for partial updates.
