I know I have most of it already written out correctly, I'm just having a hard to with the whole variable = thing

Inside the while loop. If someone could show what I am missing and explain to me how it works, that would be awesome!


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

Hey Seth,

There are a couple ways you can do this but here is how I would do it to write out lest code.

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

I initialize the variable secret with no value. This causes the while loop to become true, becuase secret does not equal sesame, and then runs the loop which would prompt the question, "What is the secret password?".

Once a user enters the correct password of sesame, then any code after the while loop will run, in this case the document.write fires.

I hope this helps.
