Removing a element, through querySelector, then selecting the element, and the .length

In this lesson he removes the last item with ‘last-child’, but he said that there in another way through, querySelector-tag-tag.length, Can someone please show me how?

What 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.
