why my code can not pass?

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.");

When I typed sesame,why "You know the secret password. Welcome." did not show up?

Your code would actually work if you type sesame, but only first time,

the reason is you don't change the variable secret for second time

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.");

this will show the prompt until you put correct answer

Thank you,but that's wired cause when I typed "sesame", it's still the "What is the secret password?" showed up,not "You know the secret password. Welcome."

this would also work better as a do while loop. it would look like this.

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

document.write('You know the secret password.');

it will "do" the prompt "while" secret is not equal to sesame. hope this helped happy coding.
