Stuck on a while loop

After practicing while loops with random number generators I got to this challenge. Now I need to make a while loop with a string. This throws me off a little.

My code won't pass because I need to asign a new value to secret inside the loop. With the numbers you would write something like "var += 1;" and then the loop continued untill false. I think I need to do something similar with this string but can't figure it out by myself.

app.js 
var secret = prompt("What is the secret password?");

while (secret !== "sesame") {
  prompt("try again");
   secret === "sesame"
  document.write("You know the secret password. Welcome.");


}

You are very close. You are passing a new value to secret using prompt(). Your problem is that you have document.write inside of the while loop. If the correct password is entered it does NOT enter the while loop.

var secret = prompt("What is the secret password?");

while (secret !== "sesame") {
  prompt("try again");
}

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

Hi LaVaughn,

This is closer! Inside the loop, secret needs to be assigned a new value from the prompt - otherwise the loop will never break, as secret is never changing.

You are so close! 

var secret = prompt("What is the secret password?");

while (secret !== "sesame") {
  prompt("try again");
   if ( /* your condition */) 
     document.write("You know the secret password. Welcome.");
}
