Earlier quoted context omitted.
Do you have any concrete examples you can link to show these differences? I'm unsure what you mean by architectural decisions made at the language level.
Maybe a good example could be the recursion pattern in Elixir. This is considered almost a base element of the language. Typically in Elixir recursion and "guards", are used instead of things like for-loops and if-else statements in other languages. Take a basic factorial function in Elixir: defmodule Math do def factorial(0), do: 1 def factorial(n), do: n * factorial(n - 1) end There is almost nothing there that isn…
That Elixir part is pretty slick. But to be fair to JS, you could also write that JS function like this:
let factorial = n => n === 0
? 1
: factorial(n - 1) * n;
