# JS Coding Question #7: Classic Fizz Buzz (one-liner 🤯)

#### Interview Question #7:

Write a function that will print from 1 to 100. Print 'fizz' for multiples for 3. Print 'buzz' for multiples of 5. Lastly, print 'fizzbuzz' for multiples of 3 and 5.🤔

If you need practice, try to solve this on your own. I have included 2 potential solutions below.

Note: There are many other potential solutions to this problem.

Feel free to bookmark 🔖 even if you don't need this for now. You may need to refresh/review down the road when it is time for you to look for a new role.

#### Solution #1: if-else (Recommended)

• A straight-forward approach using the good old if-else statements. It is nice because it is easy to implement and you can code this while you are explaining to the interviewer what is happening statement per statement.
``````  for (let i = 1; i <= 100; i++) {
// Is the number a multiple of 3 and 5?
if (i % 3 === 0 && i % 5 === 0) {
console.log('fizzbuzz')
} else if (i % 3 === 0) {
// Is the number a multiple of 3?
console.log('fizz')
// Is the number a multiple of 5?
} else if (i % 5 === 0) {
console.log('buzz')
} else {
console.log(i)
}
}
``````

#### Solution #2: Nice, fancy one-liner

• I would stay away from this on an actual interview as you would look like a leetcode material/master. You may mention that you saw a one-liner solution using couple of ternary and you are aware. Might get a bonus for that.
``````  for(let i=0;i<100;)console.log((++i%3?'':'fizz')+(i%5?'':'buzz')||i)
``````

Happy coding and good luck if you are interviewing!

I hate if..else, so i came up with this.

i try to limit if/else as well if possible. Solution looks good. O(n)

Nice and thanks for sharing! These one-liner are nice and amazing to see but not worth to spend much time and energy on as one will not present them on an actual interview.

If I go on an interview and get asked to code Fizz Buzz, i would still stick to the old if-else solution. Do you feel the same?

looks good to me! thanks for sharing.

i hardly use old school `for` iterate as well especially there are other better alternatives.

``````const fizzBuzz = x=>[x,f='Fizz',b='Buzz',f+b][!(x%5)*2+!(x%3)]
