Ha, ha, ha, ha!  All the hundreds of programs on Rosetta Code
use the division operation (of some kind).

Division is computationally expensive.

Write the answer without using division of any kind -- and no
pre-computed lookup tables either.

Let's make that:

   int i=0,j=FOO,k=BAR,v=0;
   for(i=1;i<=MAX;i++)
   {
      for(;j<=i;j+=FOO)
      {
        if(j==i){v+=1;}
      }
      for(;k<=i;k+=BAR)
      {
        if(k==i){v+=2;}
      }

Then with MAX set to 100000:
anon@lowtide:~/code/fizzbuzz$ time ./fb >fbout

real    0m8.880s
user    0m8.868s
sys     0m0.004s
anon@lowtide:~/code/fizzbuzz$ time ./ff >ffout

real    0m0.020s
user    0m0.012s
sys     0m0.004s
anon@lowtide:~/code/fizzbuzz$ diff fbout ffout
anon@lowtide:~/code/fizzbuzz$

Cool... but can any of you guys go:

for(i=0;i<1e2;console.log((++i%3?"":"Fizz")+(i%5?"":"Buzz")||i));

I chuckle a bit every time it see that idea  ;)

Tried using mod in AppleScript... and it took FOREVER (going to 100,000 it
took it several minutes, even when saved as an app -- which is much faster
than running from the Script Editor). Yeah, AppleScript is PAINFULLY slow at
stuff like this.

Curious, assuming you wanted to do this for much higher numbers, why you
would use two mods and not an if-than-else structure? If you do 15 first
then it need not check the others -- so seems good to use this logic:

    -----
    repeat with loop from 1 to WHATEVER
        if loop mod 15 = 0 then
            WRITE "FizzBuzz\n"
        else if loop mod 3 = 0 then
            WRITE "Fizz\n"
        else if loop mod 5 = 0 then
            WRITE "Buzz\n"
       else
           WRITE loop & "\n"
       end if
    end repeat
    -----

To be clear: NOT saying you are wrong, just curious.
