Using Do-While instead of While loop Challenge Task

I'm not sure what I'm doing wrong.

script.js 
var secret = false;

do{
  var secret = prompt("What is the secret password?");
  if (secret !== "sesame") {
    secret = true;
  }
} while (! secret)

document.write("You know the secret password. Welcome.");

i would use different variables to handle the password guesses and the true/false that controls the loop. right now you only have the secret variable. your loop logic also looks backwards. if i guess wrong (not sesame), secret is set to true, but ! true is false and the loop will exit.

Hi Shan Liu, Try this way...

var secret = false;
do {
  var guess = prompt("What is the secret password?");
  if (guess === "sesame") {
    secret = true;
  }
} while (!secret)

document.write("You know the secret password. Welcome.");
