"Once you understand monads, you immediately become incapable of explaining them to anyone else” Lady Monadgreen’s curse ~ Gilad Bracha"

If you'd like to go down a rabbit hole of category theory look up the phrase "A monad is just a monoid in the category of endofunctors, what's the problem?" - a fun quote that a lot of monad explanatory tutorials will quip. Not that it will help - because anyone writing a monad explanation already suffers from the first quote: they're incapable of explaining them.

I had read 30 or 35 different monads-for-Javascript tutorials/guides/explanations before I finally thought I grokked it. None of them have helped and I'm still not sure my understanding of them is correct.
