Hi Jonatan Luna

The do..while loop is when you want a specified statement to run at least once before checking the condition. In this case you want the 'do' code block to run once then test the while condition. It would go as follows:

var secret;

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

   }while ( secret !== "sesame" );

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

The prompt of "What is the secret password?" will run once, allow the user to input an answer, if they do not get it right then the prompt is repeated X number of times until the condition == true. Then the print statement will be written to the screen.

Hope this helps

Take care and Happy Coding!
