What this article misses is my favourite bit: maintainability and extensibility.<p>If this were real code two things would happen;<p>1. Someone would refactor the `fizzbuzz_word(n)` method and this would all break<p>2. Your PM would ask for a new feature &quot;multiples of 7 should be said &#x27;Wuzz&#x27;&quot;<p>So that 2 minute test becomes a 10 minute venture into real world problem solving.
