Accessors vs Dirty-checking in Javascript Frameworks

One of the many ways in which EmberJS, AngularJS, and BackboneJS differ is in how they treat their models. AngularJS uses dirty checking on Plain Old Javascript Objects (POJSO); whereas EmberJS and BackboneJS both use accessors (getters and setters) on wrapped objects. We will be exploring the ways in which these two approaches differ, and the implications these differences have when it comes to choosing which Javascript framework we we should write our single page apps in.
