kandi X-RAY | mostly-adequate-guide Summary

mostly-adequate-guide is a JavaScript library typically used in Institutions, Learning, Education, Programming Style, Functional Programming applications. mostly-adequate-guide has no bugs, it has no vulnerabilities and it has medium support. However mostly-adequate-guide has a Non-SPDX License. You can install using 'npm i @mostly-adequate/support' or download it from GitHub, npm.

This is a book on the functional paradigm in general. We'll use the world's most popular functional programming language: JavaScript. Some may feel this is a poor choice as it's against the grain of the current culture which, at the moment, feels predominately imperative. However, I believe it is the best way to learn FP for several reasons:. That said, typed functional languages will, without a doubt, be the best place to code in the style presented by this book. JavaScript will be our means of learning a paradigm, where you apply it is up to you. Luckily, the interfaces are mathematical and, as such, ubiquitous. You'll find yourself at home with Swiftz, Scalaz, Haskell, PureScript, and other mathematically inclined environments.

            How to represent functions with multiple arguments in Hindley-Milner?
            Asked 2021-Apr-14 at 13:04

            I'm reading a functional programming tutorial called Professor Frisby's Mostly Adequate Guide to Functional Programming, the author gives an introduction to Hindley-Milner and several examples about it, one of them being:



            Answered 2021-Apr-14 at 08:27

            I went through this tutorial myself and I think generally functions are assumed to be curried so f being b -> a -> b is perhaps counter-intuitive but not necessarily wrong AFAIK. (Take everything I say with a pinch of salt; I'm not an expert ;)

            However the parentheses around f itself in the reduce signature gives an important clue to the reader (at least to the JavaScript reader) that f is a function:

            Asked 2020-Aug-09 at 20:40

            Still learning about FP but I feel that I finally started to get my head around monads, specifically on using them. So here is what I have:

            Managing array of monads in fp-ts and Functional Programming
            Asked 2020-Apr-10 at 17:20

            I'm very new to Functional Programming and I'm struggling a lot with running traverse on arrays.

            When I read this book it seems that I should be able to simply traverse between Monads but I can't wrap my head around this concept with fp-ts.

            Can someone explain the following using array.traverse/sequence or any other ways please?

            1. How can I go from TaskEither to TaskEither[]>; or is there a better way to go from a single error to nested errors while keeping the typings simple?
            2. How can I go from TaskEither> to something like TaskEither> or something similar; or should we map the result of that function to turn back to Either?

            Consider the following simplified code to have a better idea what we are doing with these arrays:



            Answered 2020-Apr-10 at 17:20

            Strictly spoken, Applicative is sufficient for traverse - you don't need a monad.

            TaskEither to TaskEither[]>?



            Why is composition of identity and unary function not equal to the function?
            Asked 2020-Mar-01 at 11:49

            Chapter 5 of Dr. Frisby's Guide asserts that identity of a unary function is the function itself. That is, the last line of the code below should return true.

            However, I am getting 'false'. Why?



            Answered 2020-Mar-01 at 02:53

            I think it might depend on the language that you're using. Most languages are not equipped with a way to establish 'algebraic' equality between functions, and are likely to compare functions via their 'pointer' or 'reference', even if such is abstracted away. As a result, since your composed function would be a different function altogether (albeit with the same behaviour), it might not return as equal.

            This being said, you can probably test it by having a set of input and running both functions on it, checking the equality of the output.
