Problem Statement
What are the key strategies for optimizing Redux performance?
Explanation
Key performance optimizations include using memoized selectors with reselect to avoid unnecessary recalculations, keeping your state normalized to prevent deeply nested updates, using React.memo or useMemo to prevent unnecessary component re-renders when Redux state hasn't changed, and splitting your state into smaller slices so components only subscribe to relevant data. You should also avoid creating new object references in mapStateToProps or useSelector by using shallowEqual comparison, batch multiple dispatches when possible, use RTK Query for automatic request deduplication and caching, and consider using Redux DevTools trace feature to identify performance bottlenecks in your reducers or selectors.
