I'm also taking advantage of a few other facts in Javascript:

Methods are attributes. There is no inheritance in JS, meaning that every object has a direct reference to every one of its methods.
Identical functions are referenced (in most implementations). This means that identical code gets a reference to the existing version, not a new function.

I could store the adjacent objects as attributes, but that prevents me from expanding my object model later on if, for some reason, the getLeft() method isn't static anymore. This future-proofs me.

My criteria for good software:

Does it work?
Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
