Is there other way to reference grandParent object in javascript

Question

I have following code:

var objectParent:{
     child1:{
       test1:function(){},
       test2:function(){}
      },

      child2:{
       demo1:function(){},
       demo2:function(){},
       parent:this  // gives child2
       grandparent: .... // need to reference objectParent here

      }

    }

We can reference object by using this keyword, But what for grand object or i mean parent of parent object?

Now, i am using grandparent:objectParent to reference parent object

Is there other way like this selector to reference parentObject?

Are these my coding is bad,good or better?

Answer 1

If all your objects have a parent property that refers to their parent, then can get the grandparent with object.parent.parent.
