Had to write my own version before before I ask other people to do the same. http://c2.com/cgi/wiki?FizzBuzzTest

fizzbuzz.js

var fizzBuzz = function fizzBuzz () {
  "use strict";
  var fizzArray = [];

  var fizzNumCheck = function fizzNumCheck (num) {
    var numString = num.toString();
    var mult3 = false;
    var mult5 = false;
    
    if (num % 3 === 0) {
      numString = "Fizz";
      mult3 = true;
    }
  
    if (num % 5 === 0) {
      numString = "Buzz";
      mult5 = true; 
    }
  
    if (mult3 === true && mult5 === true) {
      numString = "FizzBuzz"; 
    }

    return numString;
    
  };
  
  for (var i = 0; i < 100; i++) {
    fizzArray[i] = fizzNumCheck(i+1);
  }
  
  console.log(fizzArray);
    
};
fizzBuzz();
