Having problem with the do while loop

Didn't just get the do while loop. Even with the example used

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

In the second line of your code, Hello value is not defined. You may want to enclose it in single or double quotes to make it a string literal.

How about the following simplified solution?

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