I am just curious why this code instead of the one in the video won't work?
if (event.target.className=== "up" && event.target.parentNode !== listUl.firstChild) {
let li = event.target.parentNode;
let previousLi= li.previousElementSibling;
let ul = li.parentNode;
ul.insertBefore(li, previousLi);
}

Try using "firstElementChild" instead.
