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

I'm trying to complete Challenge task 1 of 1 with while loops. My current code keeps returning a syntax/parse error.

My code is:

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

while(guess !== "sesame"){
  return secret
}

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

Hi Jullian,

The secret var itself is the answer to the prompt. Whatever the user enters in the prompt will be the "secret" var. So there is no need for the "guess" var. Try it like this:

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.");

Elian,

So inside the while loop, couldn't we call the variable "secret" again instead of typing it all out? or would a function needed to be created in order for that to work? Just curious to save typing.

Thanks Elian you are awesome!

Hey Nick,

Unfortunately not. In order to call the var without setting it you would need to set a return statement, but that would mean that the loop will stop ( return always stops the execution of a function ). So, as far as i know, you would have write it all out again inside the loop.

Your progam needs to ask a question until the right answer will be entered. So you need while loop and question inside.

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