clearInterval stops an interval from executing, it doesn't remove the ID that
was assigned to the interval.
>From the docs:
<quote>
setInterval:
Returns
Number - An integer that identifies the interval (the interval ID), which
you can pass to clearInterval() to cancel the
interval.
</quote>
Each time you call setInterval a numeric identifier is returned, which is auto
incremented as you can see in your example.
And this also explains why it is so important to clear an interval before
creating a new one, which was mentioned a few times here
recently.
