Fix unnecessary re-renders in React by measuring components with the Profiler to confirm bottlenecks, then selectively applying memoization strategies like React.memo, useMemo, and useCallback to optimize render performance.

Use memoization in React only after confirming a render bottleneck with the Profiler. Apply React.memo, useMemo, and useCallback selectively to avoid premature optimization and keep your application maintainable.

Yes, the React performance optimization guidance supports React 18 and 19 projects using TypeScript, including specific strategies for leveraging the React Compiler to automate memoization and reduce heavy re-renders.

Reduce bundle size in a React application by applying code splitting and lazy loading techniques. These strategies defer loading non-critical resources, improving initial load performance and overall resource optimization.

Profile React component render performance by using the React Profiler to measure render times and identify bottlenecks. This confirms exactly where selective optimization and memoization are actually needed.
