Heh. Well, perhaps relative newbies. Remember Direct-L? Some astonishingly painful questions were asked there.
I think you're on to something, though; Hype's a flexible engine and there's no immediately obvious way 'in' to it. What I mean is that there isn't an immediately obvious starting place, the first thing you do to begin scripting or creating some kind of sequential set of scripts. In the world of Director, that was the frame script. Hype's nearest equivalent is probably onSceneLoad, but that's not always immediately obvious.
Later versions of Director also shipped with an internal, interactive doc engine that provided syntax examples on the fly. The trouble here, though, is that JS is vastly expanded beyond its core functionality, and more is being added all the time by external libraries such as JQuery - so a single exhaustive reference engine is probably beyond the scope of … well, anyone.
That's got nothing to do with Hype or Tumult; JS has been evolving under the influences of various browsers, other third parties, and individuals and group of developers for, oh, a couple decades at least, and there's not a whole lot of central guidance.
It's easy to do a dictionary of a language you've created from scratch, but much harder to do a good comprehensive top-to-bottom ref on something that's continually growing.
