Hello friend. Converting code inside a while loop to a do-while loop is pretty sweet and simple

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

First u have to cut 'while(secret !== "sesame")' from the top and place it AFTER the closing curly brace. Then put the word 'do' before the opening curly brace. and WALA! u have a do-while loop!

Mark my answer as the best if i managed to help u

Here is the code that worked for me:

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

A do...while loop guarantees the execution of your loop at least once up to the while statement.
