This is my first project using javascript to navigate the API and I am jsut wondering if anyone had some advice about the best way to approach the following goal:

Iterate over all tracks in the set (excluding return and master).

Check if there is a looper device on the track.

If there is, assign an observer to the 'State' parameter (parameter 1)

repeat until 3 loopers have observers, or you run out of audio tracks.

My first hurdle: my instinct was to use a for loop to iterate over the tracks, but without knowing how many tracks are in the set, I would have trouble writing the statement. Is there a quick way to poll the set for the number of tracks? Should I use a while loop?

Second hurdle: Once we land on a track, what is the best way to iterate over the devices on a track (a similar problem to the one above).
