Nice article, thanks for sharing! Quick suggestion:

You can get to pattern matching power in this place:

  defp get_fizz_buzz_value(num) do
    cond do
      rem(num, 15) == 0 -> "FizzBuzz"
      rem(num, 3) == 0 -> "Fizz"
      rem(num, 5) == 0 -> "Buzz"
      true -> to_string(num)
    end
  end
Enter fullscreen mode Exit fullscreen mode

->

  defp get_fizz_buzz_value(num) when rem(num, 15) == 0, do: "FizzBuzz"
  defp get_fizz_buzz_value(num) when rem(num, 3) == 0, do: "Fizz"
  defp get_fizz_buzz_value(num) when rem(num, 5) == 0, do: "Buzz"
  defp get_fizz_buzz_value(num), do: to_string(num)
Enter fullscreen mode Exit fullscreen mode

Might be even nicer to skip rem(,15) in favor of rem(,3) and 5 together separately, but it will also affect the Ruby code then
