3,252 PointsConfusing loop results
The challenge asks you to turn this while loop into a do while loop. My question is about both types of loop.
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.");
What confuses me about this loop is that when I enter a word that is not "sesame" it loops twice and then displays the document.write string anyway. I can't figure out why the while loop is breaking and running the document.write().
Then when I change it to a do...while loop like this (which passed the challenge)
var secret; do { secret = prompt("What is the secret password?"); } while ( secret !== "sesame" ) document.write("You know the secret password. Welcome.");
The document.write string is displayed no matter what I enter in the prompt.
Am I missing something after the while ( secret !== "sesame" ) statement that would actually make the loop keep running until "sesame" is entered?

231,275 PointsI tried both versions, and they seem to work correctly. Both of them keep asking for input as long as I answer with something other than "sesame". And when I give "sesame", they both end and display the message.
Perhaps try it with a different browser?
