Optimizing React app performance involves techniques such as using React. memo, useMemo, and use callback to prevent unnecessary re-renders, employing code splitting with dynamic imports, and utilizing virtualization for large lists. Additional strategies include avoiding inline functions in JSX, using ...
Why Is React Performance Optimization Important? React Performance Optimization is essential for several reasons: User Experience Many studies have found that a slow and unresponsive app can result in a poor user experience. This causes the users to leave the application. Hence, it’s crucial to ...
