Hello people, I am a junior Rubyist and actually learning Elixir for fun. While I was learning some OOP design patterns for my job, I was wondering: “What about Elixir, functional and concurrent programming?” I always see things about the Gang of Four, OOP, popular stuffs like that, but for FP, I …

There are design patterns, but they are different. One video I liked when switching from Ruby to Elixir is… [🚀 Functional Design Patterns (Scott Wlaschin)] OTP is also a guide to good design with processes. It is worth learning. The FP side of Elixir and Erlang is pragmatic, You can…

[image] kokolegorille: You don’t have some tools others FP languages may have, like monad, functor. I get what you’re saying and you’re not wrong per se, however, these are abstract patterns that one can use in Elixir, they’re not enforced at the type level, nor do we have syntactic sugar for…

for the boring real-world software I write I do not feel the need for monads and the other fancy stuff. reduce and flat_map and frieds take you a long way. And using lists like [1,2,3] ++ [] ++ [4] is nearly a monad isn’t it? As for design patterns, the picture you posted is correct (Its from Sco…

[image] Mraiih: I know design patterns came to resolve some common problems in OOP, but I suppose FP isn’t perfect and some problems can occur as well Can anyone shed some light on this subject? And share some resource if needed? [image] Elixir for Programmers A fast paced video …

Friendly reminder that while Elixir is considered a functional language, the lack of auto currying makes the majority of functional programming patterns very cumbersome to use and functional composition(h = g ∘ f) is very rare in idiomatic elixir code, and thinking of elixir as a functional language…

Thanks everybody for your replies :smiley: One video I liked when switching from Ruby to Elixir is… I just finished the video, didn’t understood everything but I keep some keywords and concepts for the future! OTP is also a guide to good design with processes. It is worth learning. Thanks fo…

[image] Mraiih: I came across this image: I understand the sense that the image is trying to convey, but I don’t think it’s particularly fair: the left-hand side are concepts and the right-hand side are implementations. If the left-hand side was also implementations, it would just be “object…

That’s why there are such a enormous number of decriptions of monads :smiley:

Once you understand what a monad is, you can’t explain it.
