crocks | well known Algebraic Data Types for your utter enjoyment | Functional Programming library

I understand that monads typically don't want to unwrap the underlying value because it may or may not exist. In my use case I would like to use functional programming techniques, using ramda for a functional library and Crocks for an algebraic data structure library to write code in a not fully functional codebase. I'm typically going to be using Either, IO, and Maybe monads to write my code, but then extract the final result out of the resultant monad so I can return the value to a function that is not made to accept monads yet.

Folktale has something called getOrElse which will return a value or an undefined/error string. This is super useful and allows me to write functionally in an environment that does not expect to handle monads. Does Crocks have something similar or is there another way to unwrap an Either, IO, or Maybe?

Folktale example that I'd like to replicate in Crocks:

I have an ngrx store (in typescript) and i want in my EntityAdapter reducer to check for an action and then add to every child of my item in the store the payload of the action. Example below

We have an array of objects in the state, and each object has one property, lets call it X that is an array as well.

I'm actually learning functional programming, and I'm trying to learn & use crockjs

For now, I'm trying to implement the "monadster" program described in https://fsharpforfunandprofit.com/monadster/ .

Here's what I'm having for now (just the beginning...)
