Simpler Way

if you are trying to write dry code wouldn't this be a much simpler way to output the amount of incorrect answers?

html = "You got " + correctAnswers + " right and " + (questions.length-correctAnswers) + " wrong!"; print(html);

This was just my first idea when trying to solve the quiz, is this not the best method?

:point_right: Being "DRY" doesn't mean replacing variables with calculations.

There's really nothing redundant in either implementation method, so one was isn't more "DRY" than the other.

However, in phase 2 of the program development, the objective includes retaining both the correct and incorrect questions, so you could eliminate keeping a separate count altogether and do something like this:

html = `You got ${correct.length} right and ${wrong.length} wrong!`;

I also used string interpolation via a template literal here to make it even more compact.
