Time to wheel out another paraphrase of Greenspun's Tenth Rule (http://en.wikipedia.org/wiki/Greenspun%27s_tenth_rule)

How about:

"Any sufficiently complicated collection of libraries contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of a full framework"?

;-)

That sounds about right :) . However, you need a great degree of discipline (greater compared to other languages IMO), to write good JS. JS enforces almost nothing, so it's up to the programmer to design an application architecture that suits her, so it might not be as ad-hoc in real life applications after all.
