To people saying "backbone", stop. Backbone is a tiny abstraction that pretty much does nothing; It's the worst of both worlds: You have to use fake getters/setters but the framework is absolutely unhelpful.
Angular is more developer friendly as it avoids crappy string templates and let you program to POJOS; Programming with POJO in Javascript circa 2013 has a big performance cost that might be very noticeable in some cases (Mobile, low spec devices, sites with a lot of interaction/server pushes). Basically Angular simply DOES NOT scale by design, but 90% of websites will still be kind of ok (This gray line is exactly why I don't use Angular :) ).
