2.2 Computed Properties
Computed properties are one of Ember's stand-out features. Basically they're methods that are allowed to be used as properties. If it were Ruby, it wouldn't make much of a difference because the language makes no difference between the way you call variable names and methods. Influenced by Ruby, Ember decided to port that characteristic through computed properties.
In this lesson you will learn how to define those computed properties and how they behave in your application.
