Infinite Loops Quiz: Given the code below, what will print to the console?

I have tried every answer on this question but am constantly told it is wrong. Not sure if a bug, but I thought the answer should be 'goodbye'.

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

Hey Zaal Rottunda 👋

You've posted this question in the general JavaScript discussions so I'm not entirely sure what quiz you're referring to. Could you please share a link to the quiz you're working on?

Since you're enrolled in a Techdegree you could also reach out to our Slack channels. We got dedicated staff and moderators available there throughout the day and are more likely to get a speedy response over there 🙂

Thanks for sharing a link to the quiz! Looks like there are no duplicates in the quiz. First one is a do...while-loop: 

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

For this question the do part of the loop will always run, no matter the condition. Therefor the result for this one will be: Hello Goodbye

The other question is the snippet you shared above, which is a while-loop. 

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

This block will only run while the conditional evaluates to be true. Since false will never evaluate to be true, the code inside will not run and the answer for this question is indeed: Goodbye

Hope this clears things up! 😃
