QUESTION
I've created a menu component and I'm trying to use the useState hook to store which sub-menus are open. When the menu is closed (from the parent using props) I want to close all sub-menus and to do this I've using the usePrevious hook from the react-hanger library to determine when the main menu is going from OPEN > CLOSED . Here is my code.

hook and execute it only on isOpen
prop change
