React Performance Optimization: Memoization

Using the useCallback hook properly can lead to fewer component renders being displayed in the React DevTools Profiler flame chart. When callback functions are memoized with useCallback, child components that depend on these functions as props may skip unnecessary re-renders. The Profiler shows this optimization as fewer render operations in the visualization, with fewer components lighting up during updates, making it a useful tool to verify that your memoization strategy is working as expected.
