There are libraries for swipe gestures in the browser like hammer.js and you can probably use those, but if I were implementing this from scratch, Iโd assign a mousedown and a touchstart event listener to any element I wanted to be โswipableโ. In the event listener, Iโd save the inital touch or mouse down point as the starting point and then use mouseup and touchend events to get the end point, then handle the logic to determine which direction to swipe by comparing the start and end x and y values.
If you wanted to have something happen depending on if you tocuhed the top, bottom, right or left of the element, you could use the same approach only use the .getBoundingClientRect() method to find the center point of the element and compare that point to the touch point.
I hope this helps! Good luck!

Calviีฒ I especially liked the line from your code:
var mc = new Hammer(pad);
The pun is clever. ๐๐คฃ

I think it's possible with ReactJS framework.
