There are distinct notions of monad. Just a note.

  Is that so? Just a note.

  That's not really helpful without at least two distinct notions of monads shown.

  a data class / object is a monad if it confirms to the 3 monadic laws [1]: Left identity, Right identity and Associativity. To do this, it must implement two functions. 1. chain (also called 'flatMap', '>>=' in haskell). 2. unit (sometimes called 'of', for instance in js). Nothing more is needed to understand and implement a monad in any language. [1] https://wiki.haskell.org/Monad_laws https://wiki.haskell.org/Monad_laws
