'E' is the first parameter in function (listener). Why we use event.target instead of e.target?

It probably slipped by because the code works anyway. That's because some browsers (and clearly the one being used) will make the current event object available in the global window.event, which can be referenced simply as "event" if the name has not been reused.
But this behavior is not supported by all browsers, not guaranteed, and should definitely not be relied on. The passed-in event object should always be used instead.
Good catch!
