Yes well there are lots of better ways to code that example without promises - I just used that to illustrate the theory. The nested callbacks may have nothing to do with database interaction of course.

Thanks for the explanation, Keven; If your application is doing nested
record retrieval, then you you may end up coding nested call-backs, which
could become rather deep. So you're still in "hell", but "promises" makes
the syntax a bit more palatable.

Why not just "call" an RPG program to handle nested record retrieval, as
opposed to coding nested call-backs in Node.js?
