Prompt equal

var secret = prompt("What is the secret password?"); 
do { 
prompt = prompt("What is the secret password?"); // Why is this prompt equal to prompt("What is the secret password?");?
secret = secret + 1; 
if ( prompt == 'sesame') { secret = true; } 
} while ( ! secret ) 
{ document.write("You know the secret password. Welcome.");
}

You increment text variable. It will be always true. Your code should be, as the following:

var secret = 'sesame'; 
var pr;

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

alert("You know the secret password. Welcome.");

My code pass the challenge, but your code look shorter and thus better, but I just followed up to code I already get as start point in challenge, so I go that way.

Can you tell me where is problem with this code? In challenge said : Inside the loop, you should use the = sign to assign the value of a prompt() to the secret variable

var secret = prompt("What is the secret password?");
while ( prompt !== 'sesame' ) {
  prompt = 'sesame';
  secret = secret + 1;
}
document.write("You know the secret password. Welcome.");

You will assign sesame with prompt, if you will 

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

And why you're trying to increment "secret" value? 

secret = secret + 1;

You should compare "secret" value with prompt, that you took from input. And you shouldn't increment word, which type is String. Only in those situations, when you have counter, or something like that, you need to increment value. But in this situation you need while loop to check if value in each iteration matches secret word (while it will be not true). And counter in this loop will be result of prompt, that you take from input.

See here, how while works http://www.w3schools.com/js/js_loop_while.asp
