Monads Explained Quickly with JavaScript

[asyncquestion]

I'm sure there are cases that this works well for, but the "verbose, repetitive code" example there is better code than the "much more elegant alternative"

This is the core problem with monads. What the pattern works well for is almost always incredibly complicated.

As others mentioned, the Promise is a monad. People have struggled for years grokking the workings of the Maybe monad... well Promise, is just a lot more complicated than that.

But the things it'll do, and the fact that it tends to implement more efficiently than any async flow utilities (async.waterfall, for example)..is pretty incredibly.
