Creat 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 
var secret;
correctGues = 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.");

The error is on this line:

correctGues = false;

It should read

var correctGuess = false;

Note the extra 's'!

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.'

Sorry, I didn't see that one as well. You need to remove the var inside the do.

You have already defined the variable secret outside the loop so just need to update it inside the loop and not re-create it each time.
