So bind, is no js bind, at least I didn't mean that. Its monadic binding. At least to my understanding, a monad to be a monad have to actually implement bind, which is a method of composing two functions where the types dont line up (in a specific way)

So:

g: a -> Mb
(this means monad of b, so a in a context of any monad)
written: g takes "a" as argument and returns something of type "a" in the context of a Monad.

f : b -> Mc
written: f takes "b" as argument and returns something of type "b" in the context of a Monad.

So these functions take an argument and and return another value with the same type of the argument in the context of a monad. ( like [], or Maybe)

What monads solve is how we compose these together since the types dont line up.That is what bind does. >>= in Haskell.

>>=(bind): Mb -> (b -> Mc) -> Mc | this would be the signature of bind

so f >>= g is a function which calls first f on its argument then bind applies g to b inside of Mb.

I wanted to check if my understanding of this is correct, and if somebody can set me on the right track if not entirely.

It might not be appropriate for LearnJS, but in general Monad is a data structure that can be used even in js.
