Explaining the outcome of a JavaScript cod

There is this code in the quiz:

do {
  console.log('Hello');
} while (false)
console.log('Goodbye');

The question was: what is the outcome of this code? My answer was Hello. It was wrong because it's saying that Goodbye is printed one time as well. I didn't understand why Goodbyeis printed. Can you explain why?

The "Goodbye" is not part of any loop or conditional.

You did good spotting that because it's a "do" style loop, the "Hello" gets printed one time even though the condition is false.

But the "Goodbye" message comes after the loop, so no matter what happens in the loop, it will be printed last.
