UseEffect executes code after every render by default, but it's also great for running code in reaction to a state change. By supplying the second argument to useEffect, you may control when the effect executes.
To preserve a function across re-renders, use the useCallback Hook. When a parent component recreates a function, this will prevent unnecessary re-renders. You'll be able to use the useCallback Hook to prevent re-renders by the end of this phase.
