set (keyName, value) Objectpublic Defined in packages/ember-runtime/lib/mixins/observable.js:168 Sets the provided key or path to the value. This method is generally very similar to calling object[key] = value or object.key = value, except that it provides support for computed properties, the setUnknownProperty() method and property observers. Computed Properties If you try to set a value on a key that has a computed property handler defined (see the get() method for an example), then set()

Observers Ember supports observing any property, including computed properties. Observers should contain behavior that reacts to changes in another property. Observers are especially useful when you need to perform some behavior after a binding has finished synchronizing. Observers are often over-used by new Ember developers. Observers are used heavily within the Ember framework itself, but for most problems Ember app developers face, computed properties are the appropriate solution. You can
