This is the fizzbuzz test in literate CoffeeScript.


## What should FizzBuzz do? 

The FizzBuzz test should print:

- 'fizz' for every number divisible by 3,
- 'buzz' for every number divisible by 5,
- 'fizzbuzz' if the number is divisible by 3 and 5
- else: just print the number.

## Fun Facts

FizzBuzz is commonly used to interview programmers and test their coding skills.
Once the author [@rmetzler](http://github.com/rmetzler) was asked on a job interview
to write a "coding test". He answered by asking if the meant test was FizzBuzz. The interviewer
said yes and made a statement to not test the interviewee. The author later learned he didn't
get the job, was sad and decided on writing FizzBuzz as a learning tool. 

## FizzBuzz in CoffeeScript

FizzBuzz in CoffeeScript could look like this:

    fizzbuzz = (number) ->
      return 'fizzbuzz' if 0 == number % 15
      return 'buzz'     if 0 == number % 5
      return 'fizz'     if 0 == number % 3
      number.toString()

    for x in [1..100]
      # pretty print 
      console.log "#{x}\t->\t#{fizzbuzz x}"
