I am trying to create a do...while loop for a basic prompt. Not sure what I am doing wrong. Am I supposed to just add do

how do I add a do....while loop for the prompt

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

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

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

You've got the right idea, but you don't need to do the prompt part until you're inside the loop now.

var secret = prompt("What is the secret password?");  // Just declare the secret variable, don't set it equal to anything.

do {
  prompt("What is the secret password?"); // You'll need to set this equal to secret.
} while ( secret !== "sesame" ) // This probably needs a ; character at the end.

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

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

define secret at the top with var, but assign it inside the do loop.
