number divisible by 3 outputs fizz, by 5 outputs buzz, but both outputs fizzbuzz

fizz-buzz.js

const fizzBuzz = (num = 20) => {
  for(let i = 1; i <= num; i++) {
    if(i % 15 === 0) console.log('FizzBuzz');
    else if(i % 3 === 0) console.log('Fizz');
    else if(i % 5 === 0) console.log('Buzz');
    else console.log(i)
  }
}

fizzBuzz()
