NEED HELP !

CAN'T SOLVE THIS !! This is the code we used in the last code challenge. After learning about do...while loops, don't you think this would work better in the do...while style? Re-write the code to use a do...while loop. Important: In each task of this code challenge, the code you write should be added to the code from the previous task. Restart Get Help Check Work script.js index.html

1 var secret = prompt("What is the secret password?"); 2 while ( secret !== "sesame" ) { 3 secret = prompt("What is the secret password?");
4 } 5 document.write("You know the secret password. Welcome.");

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

Here's some hints:

  • in a "do...while" loop, the "do" comes before the loop, and the "while" goes at the end
  • you will still declare "secret" before the loop, but you wont need to assign it there
  • after the changes, there will be only one "prompt" statement

/** Creates an empty variable**/
var secret;

/** sets the variable to the code below**/
do {
  secret = prompt("What is the secret password?");

  /** tell it to run the do section until the user enters the 
correct password, and then writes the message inside of docuent.write**/

} while (secret !== "sesame")
  document.write("You know the secret password. Welcome.");
