It used to be, but it less likely with recent frameworks. I don't know Knockout. I read a little about it seems like some kind of HMVC but more like mMVC where m = mess.

Reactive can be used with KJS. KJS has observables, and the RP library will be plug to that.

Reactive Programming is about reacting to events, like bindings Model to View: if another user +fav this post, an updated will be pushed to all others and the new score will appear. You can also bind other behaviors to non-data "models" like xhr pool.
