minor mistake on nested attributes example

[renatoargh]

Hey!!! First; thank you for your awesome work, second; it seems that this line has a minor mistake:

Actual:

model = new Backbone.DeepModel({firstName:'Bob', ...

With correction:

model = new Backbone.DeepModel.extend({firstName:'Bob', ...

Thanks again!

Hi @renatoargh, thanks for the note.

Are you sure this is a mistake? Backbone.DeepModel is defined as a Backbone.Model.extend() result, meaning it "is-a" Backbone.Model constructor and that result can be called with new up with a set of attributes in its constructor.

Backbone.DeepModel.extend(), on the other hand, creates a new model type (which "is-a" Backbone.DeepModel and "is-a" Backbone.Model transitively). That expression also returns a constructor.

Calling new on a call to extend feels very weird here. Are you quite sure that's the correct way to go? (JS will parse that as new (Backbone.DeepModel.extend)(/* params */), I think, and if it works, it only works through pure luck.

Related: Some people forget that you can in fact directly create a Backbone.Model:

var myModel = new Backbone.Model({ attr1: "attr1" });

@platinumazure to be honest its been a long time since I had this problem by following the example so I can't really remember the context. I think that JS would parse my correction like this (but if not, thats what I should have written instead);

var Model = Backbone.DeepModel.extend({firstName:'Bob', ...
new Model();

Thanks for your answer, these plugins are both absolute awesomeness :)
