Are there any alternatives to something like backbone.js out there that provides some framework/structure to your front end javascript - but don\'t have any unwanted dependencie
I would recommend everyone to have a look at ember.js.
Ember is much more of a high level framework with many useful features implemented implemented out of the box. For example:
On the other hand the fact that is higher level than Backbone makes it less flexible , thus less attractive for those javascript developers that like tweaking the system and getting their hands dirty.
For those interested you can find a great comparison between the two at: http://smus.com/backbone-and-ember/
