FizzBuzz in 6 lines! What do you think of my solution?

Tonight I refactored my code and I really like what I came up with. I picked up the append to idea in a tutorial somewhere. One of my professors said that its usually better not to repeat math operations. This solution only divides by 3 and 5 once each. My original solution divided by 3 AND 5 twice each.

I hope it doesn’t come across as bragging. Ive been studying programming for awhile and feel like it is finally starting to make sense :) Id like to see a “best solutions” section on the forum. I learned a lot by looking at other peoples code.

  for (var i = 1; i <= 20; i++) {
        var result = "";
        if (i % 3 === 0)    { result = "Fizz"; }
        if (i % 5 === 0)    { result += "Buzz"; }
        if (result === "")  { result = i; }
        console.log(result); }

1. start the loop
2. create a variable to hold Fizz, Buzz, or the number. It also resets the variable at the start of each loop
3. change result to Fizz for multiples of 3
4. APPEND Buzz using += to the result for multiples of 5
5. If the result is still “” that means it was not divisible by 3 or 5, change result to the variable i ( the number)
6. console log the result variable

*** REFACTORED! Now one line shorter. ***

for (var i = 1; i <= 20; i++) { var result = “”; if (i % 3 === 0) { result = “Fizz”; } if (i % 5 === 0) { result += “Buzz”; } console.log(result || i); }

I deleted line 5 if (result === “”) { result = i; }

and added ‘|| i’ to what was line 6. I saw this used in someone else solution and was going to link to it, but I lost the page.
console.log(result || i);

Who knew id learn so much from FizzBuzz. There is even a video about TDD (test driven development) and FizzBuzz http://goo.gl/gbkhkX. I will be watching that later to see what else I can learn.

What I am excited about is programming is starting to make sense to me. I can read other peoples code then improve my code based on what I learned!
