These days it is inconceivable to make any webapp, big or small, without some kind of Javascript MV* framework. IMHO Backbone is a great choice as it isn't too opinionated to start with, but scales to more complex scenarios.
What would be "nice to have" was a part regarding memory leaks, as it can become a problem with Backbone's Views.
you mean like if you fail to unbind/remove stuff?
Great tuturial to build an application in Backbone.js! Another great contribution from @lrei
