Whoa. We've shifted from the (simpler) continuation-passing style with callbacks to this. Is this really worth it? Honestly, I don't think I like the whole idea of promises. What do we gain from this besides technical debt?

do the words "callback hell" mean anything to you?

  As with all language constructs, it's not a problem if you're judicious.

    Who needs functions. Labelled gotos are not a problem if you're judicious.

Callbacks seem simpler in a lot of these examples because they aren't really showing the power of promises. Promises allow you to chain much more complex flows of information together in a way that would result in a mess of spaghetticode if attempted using callbacks.
