3,634 PointsI 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.");
}
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.");

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

3,634 PointsI 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!!

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 !

3,634 PointsTushar the code in the box wasn't the right code, it's the do while loop I wrote above it that was wrong.
