While loop challenge

I'm not sure why it isn't working. It tells me " I should assign a new value to the secret variable inside the loop".

app.js 
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.");

Right now you test the input from the user once, you set the variable the first time they enter an attempt at the password. However you have no code to reassign the variable within the loop if they try again. Right now your loop will last forever because the value of secret will never change.

You don't even have to write more code at this time - you just have to refactor it a bit.

I understand what you mean, but I'm having trouble actually applying the syntax. i have something like this now:

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

while (secret !== "sesame") { prompt("What is the secret password?"); if (secret === "sesame") { answer = true; alert("Correct password!"); } }

document.write("You know the secret password. Welcome.");

This still hasn't worked.

Like I said earlier - you don't have to write any new code - you just have to refactor (move stuff around)

Think about the variable you are testing, and how that variable is set. Should it be set statically once or dynamically?

(Let me be clear, that I don't think just giving someone the answer when they have a problem on the code challenges does them any good)
