For instance, a root element of our own JS-based menu may trigger events telling what happens with the menu: open (menu open), select (an item is selected) and so on. Another code may listen for the events and observe what’s happening with the menu. We can generate not only completely new events, that we invent for our own purposes, but also built-in ones, such as click, mousedown etc. That may be helpful for automated testing.
