You can't set a variable equal to a loop, you will need to define it before the loop and then inside the loop set it equal to prompt like so 

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

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