Fizz Buzz!

Just curious, but i wonder if anyone else has used a different method than i did for the Fizz Buzz challenge.

Here's what i did:

for ( i=1; i <= 100; i++ ) { if ( i % 3 === 0 ) { console.log("fizz"); } else if ( i % 5 === 0 ) { console.log("buzz"); } else { console.log(i); } }

If you're trying for smallest amount of code this works:

for(i=0;i<100;)console.log((++i%3?'':'Fizz')+(i%5?'':'Buzz')||i)

You'll notice if you pass your loop into the console that you won't actually see "Fizz Buzz" on multiples of 15. That's because your loop is structured to call "fizz" first and then increment the value of i.

Try something like this: for ( i=1; i <= 100; i++ ) { if (i % 15 === 0) { console.log("Fizz Buzz")} else if ( i % 3 === 0 ) { console.log("fizz"); } else if ( i % 5 === 0 ) { console.log("buzz"); } else { console.log(i); } }

i chose a different way to do the assigment. Thanks for pointing out my oversight!

var i = 1;
var inc = function(){ i++}
do
{
    if ( i % 15 === 0 ) 
    {
        console.log("fizz buzz 15");
        inc();
    }
    else if ( i % 5 === 0 )
    {
        console.log("buzz 5");
        inc();
    }
    else if ( i % 3 === 0 )
    {
        console.log("fizz 3")
        inc();
    }
    else 
    {
        console.log(i);
        inc();
    }

}
while ( i < 101 );

A little off-topic, but FizzBuzz is a good, small demo of how elegant Python is compared to JS:

for numbers in range(1,101):
    if numbers % 3 == 0 and numbers % 5 == 0:
        print "FizzBuzz"
    elif numbers % 3 == 0:
        print "Fizz"
    elif numbers % 5 == 0:
        print "Buzz"
    else:
        print numbers

Wondering why the instructor didn't mention the concept of the "else if ()" subset to the if/else loop? Anyway, here is what I wrote and it worked just fine:

for (var i = 1; i < 100; i++) { if (i % 3 === 0 && i % 5 ===0) { console.log("fizzbuzz"); } else if (i % 3 ===0) { console.log("fizz"); } else if (i % 5 === 0) { console.log("buzz"); } else { console.log(i); } }
