I am confused about how I can make this code a do while loop? I've tried everything I could think of. Please help:)

If you could explain as to how solved my problem that would be great too. Thank you.

Hi Andrew,

You can scrap the initial user prompt and just declare the 'secret' variable only (so you can use it within the do/while).

Then put the loop into the do/while format by cutting the conditional (while) and putting it at the end instead of the beginning. Now you'll need to add the 'do' at the start of the loop to initiate it.

Just FYI - do/while loops will ALWAYS run at least once which is why we can cut out the initial user prompt as it will run within the loop.

In the end, you should end up with something like this:

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

Best of luck,

Dave.
