JavaScript - JavaScript Monads?

A monad is a data type that has a method on it that implements what they call the bind method. If you can implement that bind method, then your data type can be considered to be in the category of monad. So if I call the function greet, and I do let greeting equals greet invoked, the variable greeting is a monad. No, the, the greet function, I think would be the monad. The concept of binding is what makes a, a container, an object, a thing that have a function that can do a binding.
