As you may know, Javascript is the world’s most misunderstood language. As a language it’s pretty nice – prototype OO, decent functional support, (almost) proper lexical scoping, etc. Some warts, but generally not too bad.

But dear god is the web browser an awful platform to develop for, and some of this is Javascript’s fault. The single threaded event model is a nuisance, it’s really hard to debug, and everything just gets in the way of everything else to produce really non-trivial interactions which break everything. Attempts to layer libraries on top which make this less awful are definitely valid, and to some extent work, but they just add new levels of incompatibilities and grossness.
