Whats wrong with my code?

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

You're getting close, but...

  • you don't need to call prompt before the loop. Just declare the variable
  • when you do call prompt inside the loop, remember to assign the return value to the variable
  • you don't need that empty if statement

thanks, man, I did it. But In order to pass, I didn't really have to return any value. What is the difference between returning a value and not returning a value?

I'm not sure what you mean. "Returning a value" is something you would do in a function or method, and there aren't any of those in this challenge.

Oh sorry, I misread, cuz I saw" assign the return value to the variable"

Right, because calling prompt by itself doesn't save the response anywhere.
