The useCallback hook is used when a component's child is rendering the same thing over and over again. Pass an array of dependencies and an inline callback. useCallback returns a memoized version of the callback that updates only if one of the dependencies changes.
UseCallback is used to optimise the rendering behaviour of your React function components, whereas useMemo is used to memoize expensive functions so they don't have to be called every time they're rendered. Those two solutions are not that dissimilar in terms of hook creation.
