Well to answer the OP's question, it will create 100 *listeners* which
each consume a certain amount of memory and each have to be tracked
and deleted if the number of observed items on the page changes after
load. In contrast, a single listener that's listening for a bubbled
event will only consume 1x listener memory, and will be relevant no
matter how many child elements are beneath its scope. I use this
pattern a lot for pages where I am updating the page after load:
adding or removing elements that I need to observe.
But as I mentioned earlier, form element events do not bubble
predictably in my experience.

In my understanding, it will generate one event each time a field is
blurred, not 100 events each time a field is blurred. Each field gets
its own listener.

Question ..
Let's say I have 100 input fields, type = text. I want to put a
onblur
on all of them and pointing to the same function.
So I've used
$$("input") and invoke a blur.
This works .. but my question is .. will this generate 100 events? So
will my memory get filled with 100 on blurr events?
Would it be the same if I just Even.subscribe 100 times?
