I am considering to use either Knockout or Angular or Backbone for my personal project. I need to build some bigger, longer-running client-side interactions to go with my server-side stuff.
I want a simple and effective way to manage data-driven user interfaces.
Which framework would you choose to solve my problem described above based on the feasibility as well as the performance aspect?
It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.
Are you doing heavy DOM manipulation? I would use jQuery and Backbone.
Very data driven app? Angular with its nice data binding.
Game programming? None - direct to canvas; maybe a game engine.
