JS object accessing private variable as an object

Question

Self-references in object literal declarations

Given this object:

var OBJ = (function(){

    var dom = {
            prop1 : 'something',
            prop2 : 'something',
            prop3 : prop1
        }

    return dom.prop3;

})();

How would i go to achieve the prop3 reference (ideally without creating a method) ? i tried:

this.prop1, dom.prop1, this.dom.prop1

You can't access the properties of an object before you have finished creating it. Create the object, then assign additional values.

var dom = {
        prop1 : 'something',
        prop2 : 'something'
};
dom.prop3 = dom.prop1;
