Need help with the directions on this assignment. Not sure what is needed in do loop?

Prompt says to call the variable.. how do you do that?

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


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

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

//approach is fine
//when I was also doing, I was doing, I did not get, first attempt, from the bummers,
//I was able to get it right
//it is always better to do something, make a mistake, and get some direction from that mistake
//so what I did was like
// having var secret = prompt("What is the secret password?"); on both top and in do {}, for that it gave me a bummer
//then I corrected it
//after that it mentioned, you should not prompt in while {}
//and corrected it
//so. I'd suggest you try make a mistake and learn

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

do {

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

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

Hei Jennifer Riess , one way to the solution would be if you declare an empty secret variable before the loop .

like this:

var secret;

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

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