Backbone subview handling can be a real pain and memory management has to be kept in mind. Which is one of the main reasons why EmberJS was created. Sometimes I wonder why backbone is still getting so much love when saner alternatives (Ember, Angular etc.) have been around for so long. Is it only inertia or is there perhaps a need for a framework in the middleground between backbone and ember (in terms of abstraction)?
