I am having a terrible time getting the following code to work:

var foo = {
bar : "bar",
fooTwo : {
bar : foo.bar
}
}

When this code runs, I am told that foo.bar does not exist in line 4. Why am
I getting this error?

Most probably because the JS interpreter hasn't finished creating foo
yet, so it can't access its properties.

var foo = { bar : "bar"};
foo.fooTwo = { bar : foo.bar };

Works and is shorter.

That makes sense. Thank you
