Hello Friends,
Welcome to Part 07 of The React JS Hooks Tutorial Series in Urdu/Hindi. Today in This React JS Hooks video tutorial, we are going to learn How to use useMemo Hook with Examples.

with useMemo you will Pass a “create” function and an array of dependencies. useMemo will only recompute the memoized value when one of the dependencies has changed. This optimization helps to avoid expensive calculations on every render.

Remember that the function passed to useMemo runs during rendering. Don’t do anything there that you wouldn’t normally do while rendering. For example, side effects belong in useEffect, not useMemo.
