backbone-emulate-collection

Mix in methods from Underscore, for iteration, and other collection related features. Borrowing this code from Backbone.Collection.

It works by taking an object and a property field, in this example 'list', and appending collection functions to the object so that it can delegate collection calls to its list.

Object Literal

var obj = {
  list: [1, 2, 3]
}

emulateCollection(obj, 'list');

var double = function(v){ return v*2; };
console.log(obj.map(double)); // [2, 4, 6]

Function Prototype

var Func = function(list) {
  this.list = list;
};

emulateCollection(Func.prototype, 'list');
var func = new Func([1,2,3]);

var double = function(v){ return v*2; };
console.log(func.map(double)); // [2, 4, 6]

For more information about the proxied methods, see the Underscore.js documentation.
