# This is a complete example of FizzBuzz 
# using an assert method to test my code.
# Essentially, all the assert method does is
# throw an error if my expectation evaluates to false

# an even simpler way to test would be by just using puts.
# for example: puts fizzbuzz(5) == buzz will print out true to my terminal
# if something prints false that means its a failing case
