Backbone 1. Learning is relatively easy (I can’t give Hours, for my first code I needed like 2h, for totally understanding the whole lib in depth (at least possible) probably 1 or 2 Months) 2. 1 (Relatively much Boilerplate code) 3. 1-2 (depends on your skills and if you use any extensions that help you structuring your code) 4. It is easy to understand and to extend. I work a lot with interactions like Drag/Drop, custom Widgets etc. Using those was a chore in other frameworks (and needed much binding code and/or extensions), in Backbone it can be just bridged to jQuery (UI).
