The idiomatic solution to what? Ember.js and other frameworks exist to provide a basic structure for heavy client-side applications. Namely, a way to separate your "models" from your "views", if that's something you think is worth doing in your application. JavaScript is a language, not a framework, and thusly provides none of this structure. "Event-driven programming" and "CPS" are just idioms that can be used within JavaScript. If you don't like the way the Ember framework is structured, that's fine! But you probably have a personal style that you use in your applications that could be distilled into some kind of framework, and there's more to it than "CPS".
