I think the actual purpose of useMemo() is different, instead of relating it to slowness. If during next renderings the dependencies don't change, then useMemo() doesn't invoke the function but returns the memoized value.
But if dependencies change during re-rendering, then useMemo() invokes the function, memoizes the new value, and returns it.
That's the essence of useMemo() hook.
