You don't always need to use a counter or specify an exact number of times that a loop must run. Javascript Loops

You don't always need to use a counter or specify an exact number of times that a loop must run. All you need is a condition that evaluates to false at some point so that the loop can end.

The code in script.js opens a prompt dialog that asks for a password and assigns it to the variable secret. It also displays an alert dialog. Currently, no code checks the password.

Add a do...while loop that keeps displaying the prompt dialog until the user types 'sesame'.

here's my answer that it's not accepting:

// Display the prompt dialogue while the value assigned to secret is not equal to "sesame" let secret; do { let secret = prompt("What is the secret password?"); } while (secret !== 'sesame');

// This should run after the loop is done executing alert("You know the secret password. Welcome!");

Is this a question?

I assume you're asking why

let secret; 
do {
 let secret = prompt("What is the secret password?");
}
while (secret !== 'sesame');

alert("You know the secret password. Welcome!");

doesn't work?

It's because of the extra let in your do. By having let secret = prompt() instead of secret = prompt you are making a new locally scoped variable called secret (let's called it do-secret) which is different from the globally scoped secret (let's call it global-secret). Instead of overwriting global-secret it makes it own do-secret. So the secret in while will always stay undefined, because that one refers to the global-secret and not the locally scoped do-secret.

To fix this, simply get rid of the let in front of secret = prompt()

Try this - 

// Display the prompt dialogue while the value assigned to `secret` is not equal to "sesame"

let secret;
do {
     secret = prompt("What is the secret password?");
} while (secret !== 'sesame');


// This should run after the loop is done executing
alert("You know the secret password. Welcome!");```

let secret; do { secret = prompt('what is the secret password'); } while ( secret !== 'sesame' ); // This should run after the loop is done executing alert("You know the secret password. Welcome!");

This worked for me
