var baseController = {
  baseObject: this(??), 
  item: {
    render: function(u){..}
  },
  itemList: {
    render: function(il){
      il.forEach(function(v,i,a){
        ???.item.render(v);
      }
    }
  }
}

userController = clone(baseController);
groupController = clone(baseController);

How should I structure the code to be able to reach 'baseController' from anywhere down the hierarchy?
Update, I realize that the var with the name 'baseController' is available in this example, however I would like to be able to not be dependent on the naming of the object literal.
