useMemo and useCallback


const memoValue = useMemo(callback, optionalArgumentList);

Where :

  1. memoValue : Return memorized by useMemo.

  2. callback: Function that is executed one or more times according to optionalArgumentList.

  3. optionalArgumentList: Array of arguments that controls the execution of callback, if an argument of optionalArgumentList changes it will trigger that callback is executed again.


Hook that allows you to memorize a callback so that it keeps its scope

const memoCallback = useCallack(callback, optionalArgumentList);


  1. memoCallback : Return memorized by useCallback.
