Computed properties are an important feature for any ember.js developer to master. This talk offers an overview of a particular subset of computed properties: array computed properties, which allow for partial recomputation. This is the feature that saves, for instance, `Ember.computed.filterBy` from having to completely recompute the filtered array when an item is added to its dependent array.
