Ember supports observing any property which also includes computed properties. Observers are something which contains the behavior that reacts to the changes made in other properties. Observers are used when we need to perform some behavior after a binding has finished synchronizing. New ember developers often use observers. Observers are mostly used within the ember framework and for that; computed properties are the appropriate solution. An observer can be set on an object using the following syntax- “ember.observer” Observers in ember are synchronous. They will fire as soon as they observe a change in of the properties. And, because of this, it is easy to introduce bugs where properties are not yet synchronized.
