useCallback

It reduces memory consumption by memoizing functions
It increases memory consumption due to memoization overhead
useCallback can improve performance by preserving function identity between renders, but it does not reduce baseline memory usage. React keeps the cached function and dependency list so it can return the previous function when dependencies have not changed, and the function passed to useCallback is still created during rendering.
It has no impact on memory usage
It depends on the number of dependencies
