FizzBuzz in Elixir

Here’s the result of a recent junior dev coding dojo, tackling fizz buzz in a totally new language for us - elixir.


defmodule FIZZBUZZER do
  def fizzbuzz(value) when rem(value, 15) == 0 do
    "FizzBuzz"
  end
	
  def fizzbuzz(value) when rem(value, 3) == 0 do
    "Fizz"
  end

  def fizzbuzz(value) when rem(value, 5) == 0 do
    "Buzz"
  end
	
  def fizzbuzz(value) do
    value
  end
end
	

Everyone’s minds were blown with the inside-out-ness of the solution, providing several different implementations with the matching code “outside” of the body of the function.

We ran the dojo using the wonderful cyber-dojo TDD tool (and forgot to change the name of the module away from the default Hitchhiker’s Guide to the Galaxy naming convention).
