False impression min 3:16

In min 3:16 it looks like mouseover deletes the entire list. It we put the mouse directly in the last item you will see that that is not case.

This made me stop the video and try to understand the code. ;)

As each item is removed, the next item moves up, and therefore under the mouse. So even though the code removes just one item at a time, moving the mouse over the first one causes a "cascade" effect that removes them all.
