Can this skill help with large dataset performance?

Yes, it provides implementation patterns for virtual scrolling using libraries like react-window, ensuring only visible elements are rendered in the DOM.

How does this skill help reduce React re-renders?

It implements React.memo for component memoization and useMemo/useCallback to maintain stable references, preventing child components from updating unless their specific dependencies change.

Does it include performance monitoring tools?

It provides standardized patterns for the React Profiler API to measure render timing and identify specific components causing performance regressions.

Does it support code splitting?

Absolutely. It includes best practices for React.lazy and Suspense to split your bundle by route or component, significantly improving initial load times.
