Stuck on this code challenge of rewriting while loop to do...while loop.

I ran my code through Sublime text and opened it in the browser. It worked on the second time I guessed in the prompt dialog box though. =(

script.js 
var secret = prompt("What is the secret password?");
var guess;
var correctGuess = false;

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

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

Why are you prompting "What is the secret password" twice? You could just declare the variable once within the do while loop.

Also, whichever variable you put their answer inside, that's the variable you should be checking if it is "sesame" inside your "if" loop. So write now you don't need a variable called "guess", you could just check to see if secret contains the string "sesame", because that's where you're putting your answer. Or else just put the return value of prompt inside the guess variable and do it that way.
