No one else has mentioned using a view manager/factory to handle the life cycle of views?

instead of

  var view = new SomeView(options);

  view.render();

we do

  var view = Vm.create('some descriptor', SomeView, options);

  view.render();

The factory/manager can do many things! List out active views, clean up all views at any stage during their life cycle, default cleaning methods etc etc

Agreed. Always keep SRP in mind. In effect, this is IoC for views. Having a separate manager to manage views and their lifetimes is very useful. Need a popup dialog view? Manager handles it. Views have prerequisite views (like sign in, or loading)? Manager handles it.
