You don't need to use prototypes in order to bind a custom method in your barebone object.

Here you have an elegant example that don't pollute your code avoiding redundant code

var myobj = {
  title: 'example',
  assets: 
  {
    resources: ['zero', 'one', 'two']

}

var myfunc = function(index)
{
    console.log(this.resources[index]); 
}

myobj.assets.giveme = myfunc

myobj.assets.giveme(1);
