Create a 'do...while' loop

This is the code we used in the last code challenge. After learning about do...while loops, don't you think this would work better in the do...while style? Re-write the code to use a do...while loop.

script.js 
correctGuess = false;

do {
var secret = prompt("What is the secret password?");
  if( secret === sesame ) {
  correctGuess = true;
  }

}while ( ! correctGuess )
document.write("You know the secret password. Welcome.");

Hey!

You are assigning the var secret to a var named sesame which doesn't exist. You need to wrap sesame in single or double quotes because it is a string, like so: 'sesame'.

Also, make sure to declare secret as an empty variable outside of the loop, like so:

var secret;

Then inside of your loop you can set the var secret to the prompt method.

Hope this helps!

It seems that you also need to place 'var' before correctGuess on the first line because you are declaring it for the first time. Good luck!

Still did not work. Error message says 'Bummer! You should declare the secret variable before the loop. Otherwise, you re-create that variable each time through the loop.'
