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 like the others sets the wrong expectations. Sure, they’re good as inspirations, but I don’t find much value in them in Elixir other than having the vocabulary to understand why flat_map is called flat_map.
I find the philosophy of Clojure, ie the idea of data > functions, and thinking of data transformations rather than function compositions, is more helpful(see Ecto’s Changesets, Plug’s Conn, Ecto’s Multi and so on for inspiration). I unfortunately don’t have a list of resources right now, I’d like to compile some at some point or write down my opinions sometime, but I just wanted to point that out
