what if i have an array of paths created? and everytime i click undo it will remove them 1 by one

[Oscar Prom]

var paths = [path1, path2, ... ]; // this is your array of paths

// define your undo function

function undo() {

  var path = paths.pop();

  path.remove();

}

// connect your undo function and button

document.getElementById('undo-button').onclick = undo;

.pop() is a standard function of arrays in JavaScript that removes and returns the last item of that array. You can read more about it in the MDN docs.
