in a previous question to this quiz the while loop didn't run because the condition was (false), i thought it had to be (true) to run. But in this example it runs when (false)??

Given the code below, what will print out to the console?
do {
console.log('Hello');
} while (false)
console.log('Goodbye');
If so, this runs because in a do...while
statement, the do always runs at least once before it checks the while statement. Had the while statement been true
, it would run until the while statement became false due to a conditional statement in the while loop, or run Infinitely.
Is that the question? If not, please provide the question...
