This is Heading 4

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.

This is code

for (var i=1; i <= 20; i++) {
  if (i % 15 == 0)
    return "FizzBuzz"
  else if (i % 3 == 0)
    return "Fizz"
  else if (i % 5 == 0)
    return "Buzz"
  else
    return i
  }
