'How to code Mouse events to Touch Events for mobile using div class?

basically I want the mouseevents to work on mobile through the use of touchevents.

On this :

I'm really lost there... I think i need to put each document.addEventListener("touchstart" /"touchmove"/"touchend")

document.addEventListener('mouseup', grabOff);

But how deal with the console.log ?

Thank you for your help, i really appreciate, all the best
