Answer 1

The answers above have already explained how setInterval returns a handle, and how this handle is used to cancel the Interval timer.

Some architectural considerations:

Please do not use "scope-less" variables. The safest way is to use the attribute of a DOM object. The easiest place would be "document". If the refresher is started by a start/stop button, you can use the button itself:

Start

Since the function is defined inside the button click handler, you don't have to define it again. The timer can be resumed if the button is clicked on again.
