As someone who has never really understood monads (or tried that hard to) but who has done a good amount of Javascript programming, I really like the description of a monad as a series of nested data structures describing the next steps of a project.
Ultimately, that's very similar to what old-school ways of declaring Promises do in Javascript. You're creating a data structure that you then attach a new function to execute with the results.
There's "Functional Programming Jargon" which explains all these concepts in Javascript: https://github.com/hemanth/functional-programming-jargon
