how do you find touch coordinates with JavaScript?

touchstart touchmove touchend https://code.sololearn.com/WO8wrPV40Fzn/?ref=app for reference check this code

what did you mean by 'touch'? only digital touches? any pointer click (mouse/stylet/touch)? anything else (shapes intersections...)?

what would a program that senses a touch on the screen of my phone and stores the position of the touch in a variable look like? I'm not sure what you mean with digital touches and mouse/stylet/shapes intersections, sorry
