And abstracting over the JavaScript doesn't release a person from the 
obligation of already knowing the JavaScript that you're abstracting 
over either. I think I'd have to agree with you that there is no blanket 
way of abstracting over it so that you're saving effort in all 
situations. There are some situations where Lukas's work in Scriptaclous 
was impressive in that you'd write a class and then pop, pop, pop add 
attributes and you're on your way. I remember translating an AJAX Hacks 
book example to his Scriptaculous and being impressed by the brevity.

At STIC Eric Clayberg was using HTML5 2D canvas examples incidental to 
his Dart presentation. Afterward I found a library called jCanvas[1] 
that is a plugin for jQuery. I'd like to make some classes abstract over 
specs for shapes:

   fillStyle:  "#000",
   x:  50,  y:  50,
   width:  200,
   height:  100,
   fromCenter:  false

would become something similar to one of Lukas's classes with a few 
attributes. And then I'd like to code Breakout [2]. That'd be nifty.
