I need help with my code, why am I getting the prompt twice?

var secret = prompt("What is the secret password?"); var secretAnswer = false;

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

script.js
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.");

Or you can use a 'do while' loop here. It will pop up a prompt at least once. Then as your while part suggests, it will keep on bugging the user unless he enters "sesame".

You are asking it before the loop, and then again inside the loop.

Change the first line to just: var secret = "";

I ended up changing it to var secret;, I realized that I only needed to declare, not define it. Thank you guys so much for the support, I was pulling my hair out on that on last night!!

"I was pulling my hair out on that on last night!!"

Congrats, I've realized one thing when I want to pull my hair out and then I solve it it's an awesome feeling and it's good you want to understand the logic behind the code rather than just copy-paste stuff. Nice to meet you ! :wink:

Tushar the code in the box wasn't the right code, it's the do while loop I wrote above it that was wrong.
