Actually this takes the place of code like this:
(person2 && person2.address && person2.address.zip) ? person2.address.zip :
"no zip";
You can also use an if statement if you want.

I don't think it should impact the performance of the code in this case. You
will create all of the empty objects in the worst case scenario, and while
created and not referenced, the objects will be garbage collected anyway.
It's a bit unreadable imo, but it works.
