Why my answer didn't work? (While Loop)

So, it said "Bummer"..

But when I tried my code on the Console, it works!. It loops until it gets the password "sesame", then print it out something.

Where did I got it wrong? Thankyou

app.js 
//var secret = prompt("What is the secret password?");
while ( secret !== "sesame") {
  var secret = prompt("What is the secret password?");
}
if ( secret === "sesame" ) {
  document.write("You know the secret password. Welcome.");
}

You have a couple of issues going on, and it's mostly due to the challenge it's self. first you need to have the prompt appear prior to the while loop, so you need to not have that commented out. second you need to remove the if statement as there is no need for it to complete the challenge. its asking to repeat the prompt if not sesame. the challenge reads this as false because its not needed for the challenge to work. after the while loop have the document.write function the same, and after that you should be good to go.

I don't actually believe there is an issue with the way you've coded it, but according to the automated hint, the var keyword should only be used once, at the top of the file. Including the var keyword in a loop means the variable gets declared (as distinct from merely being assigned) over and over again, which, while not an issue in practice, isn't much loved by the linter. So, it really boils down to a stylistic issue, but what you're looking for is something like this:

var secret;

while (...) {
  secret = ...;
   ...
}
