Why does this JS prompt terminate the while loop it is inside of?

This while loop will only iterate once when run. If I replace prompt("Enter anything") with a value, the loop functions properly. How can I use a prompt with a while loop and prevent it from breaking the loop?

var c = 0
while (c < 3) {
  var p = prompt("Enter anything")
  console.log([c, p])
  c++
}

Your code snippet works just fine. – xehpuk Oct 23 '20 at 15:46

When I run it, it works fine, prompting 3 times. – Heretic Monkey Oct 23 '20 at 15:46

In the snippet the loop does continue as expected. It just stops while you are filling out the prompt since prompt & alert stop all javascript from being processed when they are open. – imvain2 Oct 23 '20 at 15:47
I think what Uncle Slug means is that the console.log()s happen only after the third prompt finished – Félix Paradis Oct 23 '20 at 15:47
Are you [seeing a only a single iteration on JSBin](https://stackoverflow.com/q/59523031)? – VLAZ Oct 23 '20 at 15:48
@VLAZ yes, only a single iteration on JSBin – Uncle Slug Oct 23 '20 at 15:51
@VLAZ yes! Adding ```// noprotect``` after the prompt worked – Uncle Slug Oct 23 '20 at 16:00
