In JavaScript Loops, we are never told what the input is so how are we supposed to figure out what the output will be? while (false) { console.log('Hello'); } console.log('Goodbye');

For the quiz question that you've posted, the condition in the while loop will never evaluate to true, as false is NOT true. Therefore, the code within the code block will never run. Essentially, the console.log('Hello'); is unreachable code. If that doesn't make sense, let me know and I'll try to explain it.
Anyhow, because the console.log function inside the code block will never run, 'Hello' will never print to the console. The statement that appears after the while loop is console.log('Goodbye'). Because that second console.log function is outside of the loop, it will run and 'Goodbye' will be printed to the console.
Hope this helps you to figure out the correct answer.
