Ah, the mystical world of #functors, #applicatives, and #monads – where programmers gather to discuss #concepts only they pretend to understand. 🤔🎩✨ Don't worry, this article assures you that knowing #Haskell isn't necessary, but let's be honest, without it, you're basically reading a recipe in Klingon. 📜👽

함수를 값에 적용하는 작업을 함수, 값으로만 나누는 게 아니라, 적용도 따로 분리한다.함수, 값, "적용"주인공 같은 함수, 값에 가려 조연 같던 "적용"을 주연으로 끌어 올려 다양한 구현과 일반화를 시도하다 보면 Applicatives, 모나드, Arrow 다 튀어 나온다.

함수를, [있을지 없을지 모르는] 값에 적용할 때 펑터 를 쓰고,
[있을지 없을지 모르는] 함수를, [있을지 없을지 모르는] 값에 적용할 때 #Applicatives 를 쓴다.

(+1)을 Just 1에 적용
Just (+1)을 Just 1에 적용

연산자를 잘 정의하면, 둘 다

(+1)을 1에 적용
과 비슷한 모양을 만들 수 있다.

실무에선, 이들을 비슷한 모양이 되게 할 수 있음이 중요하다.

#unison is super interesting to me. I recently visited their discord server and found out about #abilities
Unison gurus say abilities completely eliminate the need for #monads (reportedly they do still miss #applicatives though).
I wish I could use it as my daily driver but I’m not nearly skilled enough to build the world for each app I want to make.
Once it catches on, though, the concept of #frontend and #backend will go away overnight.

Exploring Advanced Functional Programming Techniques in Haskell: Monads, Functors, and Applicatives

Functional programming offers a powerful paradigm for writing expressive and maintainable code. Haskell, a pure functional programming language, is at the forefront of this paradigm, providing robust tools for handling complex problems with simplicity and elegance. Among these tools, monads, functors, and applicatives stand out as foundational concepts that enable advanced functional programming techniques. In this post, we’ll delve into these concepts, illustrating how they can be utilized to write cleaner, more modular code.
