A monad is anything you can flatmap with

The monad of list is you flatmap a list on a list and instead of getting a list of lists, as you would if you just mapped, you get a single flattened list

The monad of Result is you flatmap many function calls (like http requests or whatever) on each other and instead of getting many results, you get a single flattened result

Most of you already know this, without necessarily even knowing what a Monad is

Monad literally just means "one thing" - you take many things, and flatmap them into one
