Ember.Application.create vs Ember.Application.extend

I noticed that in the app.js file produced by Ember CLI (v0.1.12), they're using:

var App = Ember.Application.extend({...})

but in the introduction guide, they're using:

window.App = Ember.Application.create({...});

Is there any difference in outcome between these two (create vs. extend) ways of creating an Ember application?

As documented in the Ember documentation extend Creates a new subclass, while create Creates an instance of a class.

The main difference is that by using extend

you can override methods but still access the implementation of your parent class by calling the special _super() method

but create does not afford that ability.

The linked docs have good code examples specifically with regards to your question.

See

The create() on line #17 creates an instance of the App.Soldier class. The extend() on line #8 creates a subclass of App.Person. Any instance of the App.Person class will not have the march() method.

and the code proceding that quote.
