Below is the code for the last code challenge. This would work better as a do...while loop. Re-write the code using a do

I need help figuring this one out

  • You need to declare the secret variable in the global scope, but you don't need to set it to the prompt until the do section.
  • You want the document.write() after the do/while loop has completed.
  • You need to have an expression for your while to test.
var secret; // Declare this here so it's accessible in the global scope

do {
  secret = prompt("What is the secret password?"); // Keep doing this
}
while ( secret !== "sesame" ); // While secret does not equal "sesame"

// When secret does equal sesame, exit the loop and write to the document
document.write("You know the secret password. Welcome.");
