I'm am confused with how to construct a do while loop in this challenge...

I have had an attempt at trying to convert from a while loop to a do while loop as instructed but I missing some code for sure. Any pointers as to how to move forward/approach this challenge would be very valued. Many thanks for your time.

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





do {    

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

} while (secret !== "sesame" )
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">

You can't change the password with parseInt. It will result with NaN. Declare the secret variable outside the do while loop with no value and set the secret value using prompt inside the do while loop.

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

It is correct ot set the variable 'secret' with nothing in it outside the do...while loop but because it is a do while loop there is no need for the if statement in the code - it can simply be:

var secret;

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

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

The if statement is not necessary as the code below the loop will run only when the condition for the 'while' loop is true.
