Glitch found in a question->while loop to move the prompt again and again ,until got the answer!

var secret = prompt("What is the secret password?");
 var count=0;

   while( count!==1)
   {         if(secret.toUpperCase()==="SESAME")
            {   
               count+=1;

            }

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

   if(count ===1)
   {
     document.write("You know the secret password. Welcome.");
   }

[MOD: added ```javascript formatting -cf]

In order for the while statement to run, the given condition must be true. But it doesn't have to be a number - it can be a string match or a boolean statement. The prompt is supposed to appear until the user gets the password (tries don't need to be counted when using while).

Instead of var count = 0

try 

while (secret !== 'sesame') {
  secret = prompt ("That was not the password. Please enter the secret password");
}
