Create a 'do...while' loop (JavaScript loop Array and Objects)

Question

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.

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

Answer

do { guess = prompt('What is the secret password?'); guessCount += 1; if (guess === secret) { correctGuess = true; } } while ( !correctGuess ) { document.write("You know the secret password. Welcome."); }

Response Bummer! There was an error with your code: ReferenceError: Can’t find variable: sesame

script.js

var secret = sesame;
var guess;
var guessCount = 0;
var correctGuess = false;




do {
  guess = prompt('What is the secret password?');
  guessCount += 1;
  if (guess === secret) {
   correctGuess = true;
  } 
} while ( !correctGuess ) {
  document.write("You know the secret password. Welcome.");
}

You've gotten a bit too fancy here. For best results from a challenge, always do only what the instructions ask and nothing extra.

Here's a few hints:

you don't need extra variables, use just one like in the original code
keeping a count is not part of the challenge
you don't need a conditional if the loop expression checks the right thing
the "while" in a "do...while" ends the loop, there's no code block after it
string literals must be enclosed in quotes
