Man how can one still do such kind js code generation while not solving any actual problems of web development? I don't need a animation tool that spits out a js file(I can do that myself). I want a complete solution that can abstract away things missing or being badly designed in the javascript language.

I could do without choice of library if the tools offer would be really nice. Some little declarative animation framework, some knockout like bindings, some razor syntax templates that render both server and client side, and view models written server side and then passed to the client(including commands, compiled to js using expression tree magic or something...), THATs what I'm expecting from the HTML5 tooling story. =)
