"Given the code below, what will print out to the console?" Please explain!

How is it also going to print out Goodbye? It thought if the while condition is false, it'll never run.

Right. That code would print Hello Goodbye.

The console.log('Goodbye'); is outside of the {} and so it's not effected by the while condition.

Never mind I figured it, even though the while condition is false, it'll still run at least once because it's a do while loop, right?

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

Sorry I didn't provide the code.
