A do-while loop is best used when you want to always run the code block at least once, before evaluating a condition.

var secret; // declare the secret variable so you can use it inside the loop do { // always do the following code block at least once secret = prompt("what is the secret password?"); // execute the code inside the block... } while (secret !== "sesame"); // and THEN evaluate if secret is equal to 'sesame' - if not, run the block again until it is. document.write("You know the secret password. Welcome."); // once secret = sesame, write to the document
