Access Sibling Object from Function

I am trying to access an object (childObject1) which is a sibling object to the function (childObject2). Although this is the case, it appears as though the function cannot access childObject1 but it can access fields within it such as grandChildObject1.

parentObject: {
    childObject1: "Child Object 1",
    childObject2: function() {
          var grandChildObject1 = "Grandchild Object 1";
          console.log(childObject1);
          console.log(grandChildObject1)
    }
}

The first log prints:

undefined

The second log prints:

Grandchild Object 1

Why is the function not able to access the value of childObject1 if they are siblings?

Much like any other static methods, you would have to go though the parent object e.g. parentObject1.childObject1 when accessing it from childObject2. There is no instance of a static object hence they are not really logical siblings.

You have to use this:

var parentObject = {
    childObject1: "Child Object 1",
    childObject2: function() {
          var grandChildObject1 = "Grandchild Object 1";
          console.log(this.childObject1);
          console.log(grandChildObject1);
    }
};

parentObject.childObject2();

You need to use this. change 

console.log(childObject1);

to

console.log(this.childObject1);
