Augmenting properties/methods to an array?

Question

enter image description here

recently, i came across a question of how jQuery acts as both a function, as well as an object. the thing that made it possible was that jQuery was actually a function (hence the $()) that was attached with properties (like $.each()).

now in my project, i would want to create a model (which technically is an array of stuff), add methods to it, and return it to a variable which will hold it. is it wise to do it like this? does it interfere with anything?

//i did it like this: function createModel(name){ var model = internal.models[name] = []; model.add = function(){..logic to add to the model..} //more augmented methods here... return model; } //create a model var myModel = createModel('test'); //then i can do add myModel.add('foo');

To add to that, I don't want to mess around with the actual Array prototype stuff. I'm doing this for the currently created array.

the model i'm making is not like Backbone.js' model which is a unit of data. It's more synonymous to Backbone.js' Collection, or a Database table.

Something in that style might do, also never start a model as an array, always take a function (constructor) and a proper object they are more flexible for that.

var model = function(data) { this.data = data; }; model.prototype.getData = function() { return this.data; }; var mod = new model({foo:'foo'}); mod.getData().foo

updated my post. actually, the code is in a function that returns the newly created model for reference, as well as manipulations.
