Backbone is very easy to use as it has everything you need built in to make your life easier. It's also very powerful and flexible which allows you to do almost anything you want. If you're looking for something that will save you time and effort then backbone is definitely what you should be using. Nothing at the moment, but I think the documentation could be better. Perhaps more examples? It's not so hard once you get used to it, but the docs could be updated. I've been able to create some really nice apps using backbone. The benefits are that they're super fast to develop and test compared to other libraries like Angular.
