Just wondering if i am doing too much for this question?

Asking to re-write the code for a do while loop thinking I am adding too much or not properly describing it

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

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

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

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

One of the advantages of a "do" loop is that you will only need one "prompt" statement (the one inside the loop).

Also, there's no dot between the "while" and the parentheses in the loop syntax.
