do...while loop help

Don't load this into your browser because loops never ends. Don't know why

script.js 
ar secret = sesame;

do {
   if ( secret !== prompt("What is the secret password?"))
       document.write("You know the secret pasword. Welcome.")
}
}
while ( secret < "sesame" ) {
      document.write("What is the secret password?");
}

Do while loops take the following format:

do {
  // Do something
} while(condition);

Do while loops always run at least once. Hopefully that gets you started in the right direction!

So your format is going to be, declare empty secret variable. Then your while condition is 

while(secret !== "sesame");

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

Yes, because you should not have curly braces after the while loop, this is a do-while loop that takes the format as I said above. 

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

This is how the final answer should look, do-while loops aren't as common but I would definitely make sure you understand why before moving on, I'd be happy to provide more info or answer questions
