jQuery nor coffeescript really imply "clean" client-side code, in fact I would argue that most uses of jQuery are the opposite if you compare communities like mootools. As far as coffeescript goes you still need a good sense of structure like regular javascript, nothing new there really.

Mootools still disqualifies itself in my mind by patching around on builtins.

certainly, but that's besides the point. If you look at the jQuery community vs the others, jQuery's is filled with much much more spaghetti code

jQuery makes the DOM so dang accessible that people use it as their data, which is completely backwards. Fortunately stuff like backbone has brought back some sanity.
