AngularJS's bindings beat all 3: it works with POJOs, you don't have to write glue code, and views are augumented HTML. Not "real-time", but capable of handling that with, say, Firebase. Furthermore, its testing infrastructure is best of breed, being carefully built-in and using DI. It's incredible how often it's overlooked.
Thanks - I've been digging around through the data binding internals of these JS libs and I had indeed forgotten about Angular.
I'm comparing details on deferred updates and ease of integrating an OT-type collaboration layer. Derby's already starting to head this way and appears very promising, but I think there are subtle issues both in ShareJS and Derby's implementation. I'm curious how collaboration would work on some of these other libraries, and Angular seems to be thoughtfully architected, if somewhat large.
Yeah, it's kind of unfortunate how AngularJS seems to get mentioned relatively little when it's been evaluated by various bloggers and preferred over Backbone, Knockout, Ember, etc. It's certainly one of the frameworks I'd like to see succeed in the JS space, given its great engineering and capabilities.
Personally I'm waiting for 1.0.0 and redone documentation to come out, and then I'll dive into it.
