🔗 FizzBuzz in Elixir

This article offers a fresh perspective on solving the classic FizzBuzz problem using Elixir. The author, Leigh Halliday, illustrates how Elixir's functional programming paradigm enables a different approach than the object-oriented methods generally found in Ruby. The solution involves using a function with pattern matching, showcasing Elixir's strengths such as immutability and first-class functions. The comparison with Ruby highlights not only the differences in syntax but also the enjoyable aspects of working with Elixir as a newcomer to the language. Readers can expect to learn about the nuances of Elixir while appreciating the simplicity and elegance of its solution for the FizzBuzz challenge.

whichfizz = fn
  (0, 0, _) -> "FizzBuzz"
  (0, _, _) -> "Fizz"
  (_, 0, _) -> "Buzz"
  (_, _, n) -> n
end

fizzbuzz = fn(n) -> whichfizz.(rem(n, 3), rem(n, 5), n) end
