code will not run correctly, While loop

Hi,

I have spent a lot of time trying to figure out this question with no success. Why is my code not running? Also, please post the correct code with this question (I have already tried several times before and am getting very frustrated). Thank you

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

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

Hi Daniel,

The idea is what you want to keep on asking the user for the password until the get it correct. In this case the password is "sesame". To make things simple, you want the string "sesame", not make a variable out of it.

If the user got it wrong, you want to ask the user again for the password and then assign that value to 'secret' so that it can be checked again in the while loop condition.

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.");

Thank you Jon, your explanation coupled with a visual example made this error clear to me. It makes more sense now.

//var question=answer
var secret = prompt("What is the secret password?"); 
//while(false)
while (secret !== "sesame") {
//loop
  secret = prompt("What is the secret password?");
}
//return the following when loop is exited
document.write("You know the secret password. Welcome.");

//Therefore the loop was exited, when the while argument changed, from false to true

Outside the while loop assign sesame to true using only one equals sign and see if that works.
