I use Backbone.js at work for front-end work and have found it to be a very pleasurable framework to work with, however I can’t disagree with this post; there are many areas where you can code yourself into trouble. I think Backbone really shines when you pair with it with an application architecture like Marionette or Chaplin. An application architecture will help you by reducing boilerplate code, zombie killing, event cleanup, and more. Choose Backbone, but pair it well.
