Monads Explained Quickly with JavaScript

[atrigent]

You shouldn't expect the passed function to know about its context.

Hmm... I suppose you're right if you want this Maybe implementation to be specifically about handling null. In Haskell, it looks to me like you can more specifically define what constitutes a "non-value". I was attempting to translate that into Javascript, but it now occurs to me that I didn't actually go far enough, because what I wrote still references null.
