This lesson on Monads was the hardest one I've had to write for http://scala.zone so far. Without focusing on the finer details (yet) I've tried to get beginners as close as I can to having an intuition for what a monad is (in a fifteen-minute read). https://scala.zone/courses/scala-beginner/fors/monads …pic.twitter.com/DDhBZQukuL
And I'm not sure if I've succeeded. But my approach was to try to avoid drawing any analogy with a particular everyday object (like a burrito) and focus on the types (in particular the flattening operation), because they're really the domain where monads apply.
But a good teacher can be judged on how they explain monads, so I'd like this lesson to be exemplary. If anyone has any suggestions for improvements, I'd love to know!
Tough subject. I've always thought the best description is "they are an abstraction for sequencing and flow control". I then show top down examples with Future, Either, and Option. When you describe it at the type level, you are assuming a level of knowledge that may not exist.
Also I'm a rando on the internet, so please ignore :)
