Question

Consider this,

MyApp = Ember.Application.create();
MyApp.someName = Ember.Namespace.create({
//my properties
});

I can do the same this using Ember.Object either…

MyApp = Ember.Application.create();
MyApp.someName = Ember.Object.create({
//my properties
});

So, when should I use Namespace ? Where is the difference ?

Answer 1

You can look the Namespace documentation:

A Namespace is an object usually used to contain other objects or methods
such as an application or framework. Create a namespace anytime you want
to define one of these new containers.

And the difference with an object is the destroy method, which remove the namespace from the namespaces list, as you can see here:

destroy: function() {
  var namespaces = Ember.Namespace.NAMESPACES;
  window[this.toString()] = undefined;
  namespaces.splice(indexOf.call(namespaces, this), 1);
  this._super();
}
