React useCallback vs useMemo — When You Actually Need Them

1. 1Identify situations where useCallback is necessary to prevent function re-creation on every render
2. 2Use useMemo to memoize values that don't change often, reducing unnecessary computations
3. 3Apply the rules of thumb for when to use each hook, such as using useCallback for event handlers and useMemo for computed values
4. 4Test and compare the performance of components with and without useCallback and useMemo
5. 5Refactor code to use useCallback and useMemo judiciously, avoiding unnecessary usage

Frontend developers and engineers can benefit from understanding the differences between useCallback and useMemo to improve code efficiency and effectiveness

💡 Use useCallback for functions and useMemo for values to prevent unnecessary re-renders and computations
