The FizzBuzz challenge has been around a while but I stumbled across it again after reading another unique Giles Bowkett post.

If you're not familiar with FizzBuzz, it's a little 'challenge' designed to test a candidate programmer's ability to perform a simple task. In this case, you just have to print out the numbers from 1 to 100, unless the number is a multiple of 3, when you should instead print "Fizz", 5 in which case you print "Buzz", or both 3 and 5 in which case you print "FizzBuzz".

Here's a trivial JavaScript implementation:

for (var i=1; i <= 100; i++) {
  if (i % 3 == 0) {
    if (i % 5 == 0) {
      console.log('FizzBuzz');
    } else {
     console.log('Fizz');
   }
  } else if (i % 5 == 0) {
    console.log('Buzz');
  } else {
    console.log(i);
  }
};

Pretty simple stuff, but a bit verbose. I wanted something that would fit into a tweet. It turns out that's pretty simple - this is 133 characters including whitespace, 7 within tolerance for a twitter message:
