Yep! One of my favorites (I didn't mention it because I didn't want to make it seem like I was just trying to push people towards another framework).

KO also has components now, and they work super great. Also, while bigger frameworks like Ember (which I love) are just starting to figure out and cement how they work with engines (dynamically loaded chunks of your ember app), KO supported async loading of components with RequireJS so long ago.
