Does it support the latest React 18 features?

Yes, it includes guidance on using Concurrent React features such as useTransition and useDeferredValue to maintain UI responsiveness during heavy updates.

When should I use memoization according to this skill?

The skill advises a 'profile first' approach, recommending memoization for expensive computations or components that re-render frequently with the same props, while avoiding it for simple components to prevent unnecessary overhead.

How does this skill help identify React performance issues?

The skill provides a structured workflow for using the React DevTools Profiler to record interactions, analyze flame graphs, and identify specific components causing slow renders.

Can this skill help reduce my application's bundle size?

Absolutely. It provides patterns for implementing code splitting with React.lazy and dynamic imports to ensure users only load the JavaScript necessary for the current view.
