Something that’s been bugging me for a while is the difference between using the `new` keyword versus using the `create` function. One or two Ember objects specifically mention using the `new` keyword in their documentation ([Set](http://emberjs.com/api/classes/Ember.Set.html) for example). Yet most Ember documentation uses the `create` method, and some people even mention that using `new` is just plain wrong.

So, is there any real difference between using `new` to instantiate an Ember object and using the `create` method?

I almost forgot I posted this. Anyway, I looked at the source code, and here’s the relevant snippet:

```nohighlight
create: function() {
  var C = this;
  if (arguments.length>0) { this._initProperties(arguments); }
  return new C();
}

```

So it looks like the only difference is that `create` will initialize properties (if you pass some in) and `new` won’t. So if you don’t need to initialize any properties at creation, or you need to pass the argument directly to `init`, it looks like using `new` is just fine.

It’s been a while, but I wanted to give an update to this. Today, we experienced a bug caused by using `new Ember.Object()` instead of `Ember.Object.create()`. In other words, I wouldn’t ever recommend using the `new` keyword with an Ember object subclass.
