JavaScript JavaScript Loops, Arrays and Objects Simplify Repetitive Tasks with Loops Create a `do...while` loop

I do not get where I am making mistake: I tried couple of variations but it still does not work

I have tried this code I do not have clue what I am doing wrong when declaring secret variable outside the loop.

I tried with and without "flag" variable correctGuess and it is still not working...

script.js
var secret = "sesame";
var correctGuess = false;

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


   }while( secret !== "sesame" ) 

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

A variable should only be declared once. There should be no "var" keyword in front of "secret" where it is being assigned with "prompt".

And while it won't affect passing, it doesn't need to be assigned the first time, just declared.
