Here’s the deal, I like DurandalJS. Though, I’m not going to lie, I really like AngularJS as well. These two technologies compete in many respects as they both seem to tackle the same problem. What problems are these frameworks trying to tackle? I have made a diagram of what I see to be the core developments in client side technologies, and after you view this, I will talk about where I see Angular and Durandal fitting in (note that there are a myriad of other useful frameworks that do storage, pub/sub eventing, animation, data-binding, AMD pattern ala requireJS, and a slew of other things, but this represents what I believe is the focus on today’s client-side development).
So what can these frameworks do exactly?
