      As we’re posting examples I’ll add how lovely it is in Elixir. Elixir def not putting the fun in programmer memes do. One reason I picked it because I can’t be trusted to not be the meme.

      def is_even?(n) do
        rem(n, 2) == 0
      end

        I mean, it would be almost this exact thing in almost any language.

        fn is_even(n: i64) -> bool {
            n % 2 == 0
        }
        
        even n = n `rem` 2 == 0
        
        def is_even(n):
            return n % 2 == 0
        

        etc

          Personal preference, but elixir just strikes a balance that doesn’t make me feel like I’m reading hieroglyphs so I’m actually happy to see it praised.

            I would have preferred for the function to be called mod, since it’s the modulo operation, which in math is represented with a percentage or “mod”. Most programming languages use a percentage because of that, so do a lot of calculators.

            Yeah, I agree that Elixir is a fine language for some tasks. I personally find the readability somewhat average, but it’s very maintainable (due to how it enables clear program structure), the error handling is great, and the lightweight process system is amazing.
