JavaScript JavaScript Loops, Arrays and Objects Simplify Repetitive Tasks with Loops A Closer Look At Loop Conditions

I can't figure out how to...

"You need to assign a new value to the secret variable inside the loop."

Very grateful for any pointers

app.js
var secret = prompt("What is the secret password?");


while ( secret !== "sesame" ) {

  document.write(secret);


}


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

In addition to Daniel Gonzalez's answer, I'd like to make his code even DRYer (DRY means don't repeat yourself). Instead of using a while loop, you could use a do/while loop. using a do/while loop would run the code inside the while loop once, and then running the code over and over again. So, you could say:

var secret ="";

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

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

But, it is much cleaner to do this instead:

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

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

I hope this helps! ~Alex :smile:

Hi Edward,

The challenge is asking "The code in app.js just opens a prompt, asks for a password, and writes to the document. Something is missing. Add a while loop, so that a prompt keeps appearing until the user types "sesame" into the prompt." You need to include the prompt inside the while loop as the while loop will continue to loop and continue to display the prompt until the user input in the prompt secret = "sesame".

var secret ="";


while ( secret !== "sesame" ) {

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

}


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