231,072 PointsWhat is said in the video is "we could select all the li elements with getElementsByTagName for example then find the length of the collection and use that to access the last element."
That could be done like this:
let items = document.getElementsByTagName("li");
let li = items[items.length - 1];
But this is clearly not as concise as the method shown in the video.
