FizzBuzz or BarBaz implementations with multiples of 3 and 5. And misc. coding katas.

barbaz.php

<?php
$i = 1;
do {
  $str = NULL;

  $m3 = is_int($i/3);
  $m5 = is_int($i/5);

  $str .= ($m3)?'Bar':NULL;
  $str .= ($m5)?'Baz':NULL;
  $str .= (!$m3 && !$m5)?$i:NULL;

  echo $str.PHP_EOL; $i++;
} while($i < 2001);

barbaz.simplest.js

'use strict';

var out = [], 
    current = []; 


for (var i=1;i<101;i++) {
    if (i % 3 !== 0 && i % 5 !== 0) {
       out.push(i);
       continue;
    } else {
        if (i % 3 === 0) {
            current.push('Bar');
        }   
        if (i % 5 === 0) {
            current.push('Baz');
        }   
        out.push(current.join(''));
        current = []; 
    }   
}

Rules

Iterate through numbers and when:

• multiple of 3 to echo 'Bar' (or Fizz)
• multiple of 5 to echo 'Baz' (or Buzz)
• multiple of both 3 and 5 to echo 'BarBaz' (FizzBuzz)
• otherwise, the number

Sample output

4
Baz
Bar
7

Bar
