Thank you dave for this challange took around 45-1hr to do but it was worth it. Just thinking and trying things out make you stronger and you see what works and not.

Here is my quiz you can take it and say what you think about it. If you are experience coder please look in the code and see if there is things that are not the best things to do.

I notice each question has a code block like this:

if (108 === parseInt(question1)) {
  var score = score + 1;

  if (108 !== parseInt(question1)) {
    var score = score + 0;
  }
}

Notice that the 2nd "if" will never be true because it is inside the first "if", and it is testing for the opposite condition. So the 2nd "if" can be omitted entirely for that reason, and also because even if it could ever run, it does not change the score.

But if you did want to make a change on the opposite condition, like subtract a penalty, the conventional way would use an "else" statement:

if (108 == parseInt(question1)) {
  var score += 1;   // a more compact version of: score = score + 1
} else {
  var score -= 1;   // subtract one as a penalty
}

Also, just for fun, a more compact way to do the same thing involves the ternary expression:

score += 108 == parseInt(question1) ? 1 : -1;

Alright i just wanted it to say the score will be the same if they got the question wrong guess thats unecessary.
