Elixir (with static type analysis) - gets a bit of an edge, IMO, thanks to pipes, which are way prettier than .then:

    defmodule FizzBuzz do
      @spec fizzbuzz(integer)::String.t
      def fizzbuzz(int) do
        cond do
          rem(int, 15) == 0 -> "FizzBuzz"
          rem(int, 5) == 0  -> "Fizz"
          rem(int, 3) == 0  -> "Buzz"
          true              -> inspect int
        end
      end
    end

    1..100
    |> Enum.map(&FizzBuzz.fizzbuzz/1)  #[0]
    |> Enum.join("\n")
    |> IO.puts

    #[0] function variables are a very slightly "ugly 
    #syntax" part of the language due to erlang legacy

Other stuff that's really pretty in elixir is the first class documentation. Elixir docs are out of the box prettier than ruby docs.

Compare from the official (but as a user you get these docs too):

https://ruby-doc.org/core-2.6/Array.html

https://hexdocs.pm/elixir/List.html#content

But again, it's only a bit prettier. Of course, if you try to browse both on mobile, Elixir wins handily. This is great for when you have to use the bathroom at the same time as you're in the middle of debugging and need to look up what a library module member function does, so there's some developer benefit edge too.
