JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Build a Quiz Challenge, Part 2

Trying to solve this problem a different way.

My code works the way it should, but I would like for it to show the questions I got right and the ones I got wrong vertically. I actually had it solved the other day the way I have written it without a function buildList, but I can't remember what I did because I forgot to save my work. I have been trying to figure it out and I am at a loss. Any help on this would be greatly appreciated.

Here is my code:

var questions = [
  ['How many states are in the United States?', 50],
  [ 'How many continents are there?', 7],
  ['How many legs does an insect have?', 6]
];
var correctAnswers = 0;
var question;
var answer; 
var response;
var incorrectAnswers = 0; 
var correct = [];
var incorrect = [];

function print(message) {
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML = message;
}

for (var i = 0; i < questions.length; i += 1) {
 question = questions[i][0];
 answer = questions[i][1];
 response = prompt(question);
 response = parseInt(response);
 if (response === answer) {  
 correctAnswers += 1;
 correct.push(question);
             } else {
incorrectAnswers += 1;
  incorrect.push(question);
            } 
}
document.write("<h2>You got " + correctAnswers +  " question(s) correct.</h2>");
document.write("<h2>You got these question(s) correct:</h2>");
document.write(correct);
document.write("<h2>You got " + incorrectAnswers +  " question(s) incorrect.</h2>"); 
document.write("<h2>You got these question(s) incorrect:</h2>");
document.write(incorrect);

Create a new array and if the response equals the answer then push correct to the new array, else push false

I am not quite sure what you mean by creating a new array or do I just need a new for/else statement. Also, where in the code would it go?

If I understand your question correctly, I think you could just replace

correct.push(question);

with 

correct.push(question + '<br>');

and likewise for incorrect.

That worked. I don't think that was what I did before, but it worked as I expected. Thank you so much for your help. It was greatly appreciated.
