I never understood useCallback & React Memo this crystal clear before. You've explained it so well probably i will remember it for lifetime now.

The explanation about when to use useCallback hook was so on point. Most of the videos I’ve came across, they forgot to mention that useCallback should be used only when non primitive prop gets passed to children and that prop gets used inside hook with dependency value. Thank you! Subscribed

Awesome video with clear and precise explanation about the confusing concepts like memo(), useCallback() and when to use what !!!

[IshikaAgarwal-bhry]

How do we decide when to use useMemo? Because I'm not sure if it's a good practice to wrap every child component with useMemo. For useCallback, it's clear. Thanks for the video!

Great explanation as usual!
I've one doubt. Why didn't the recommendations use Effect ran when the filters state was changed.?
But filter useffect ran when recommendations state was changed
Is it because of the ordering of the useEffect?

Which extension you are using to show errors like that? Is it eslint related or something else?
