Bugged code on "Introducing Conditional Statements: 3 objectives" quiz.

Just wanted to point out that I was stuck on Challenge 2 of 3 for at least 15 minutes before I had to ask a friend what was going on and why I couldn't figure out the Challenge task 3 of 3.

The code was:

var answer = prompt("What is the best programming language?");
if ( answer === "JavaScript" ); {
  alert("You are correct");
}

It said "You are correct!" and let me move on. But when I had left that code (assuming it was correct) it proceeded to add the else command which led to:

var answer = prompt("What is the best programming language?");
if ( answer === "JavaScript" ); {
  alert("You are correct");
} else {
  alert("JavaScript is the best language!");
}

And that didn't work. So needless to say as a beginner, I was highly confused.

Yeah, what I was trying to understand if I didn't explain it correctly was why did the first code work on challenge 2 of 3, but it didn't on challenge 3 of 3.

That is what I'm trying to understand.

if ( answer === "JavaScript" ); {

How does this work the first time, but not the second time? (I understand that the semi-colon was the issue, as I was able to finally figure it out after asking a friend.)

Yea I understand, that's really weird. It looks like there's a bug with the second challenge. That code should have not passed at all.

I'll go ahead and submit this to a moderator for further action.

Awesome. I just didn't want anyone to get caught up in confusion if that was to happen to them as well.

Thanks for the quick responses.
