Completed Quiz challenge in the Arrays section. Didn't use last function, called array w/join & tags passed to prnt().

var questions = [
    ['What is the Texas capital?', 'Austin'],
    ['What is the largest Texas city?', 'Houston'],
    ['What is the western most Texas city?', 'El Paso'],
];

var correct = [];
var wrong = []; 
var correctAnswers = 0; 
var question;
var answer;
var response;
var listHTML  //I didn't use this variable so it would be removed in real world.  Just wanted to note this.

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);  //If answers are numbers the parseInt would be used.
    if (response === answer) {
        correctAnswers += 1;correct.push(question); 
        //console.log(correctAnswers + " " + response + " " + correct[i]);
            } 
        else {
                wrong.push(question); 
                //console.log(correctAnswers + " " + response + " " + wrong[i]);

            }
        }

html = 'You got ' + correctAnswers + ' question(s) right.' + 
        '<h2> </br> You got the following questions correct. </br> </h2>' + 
        correct.join(' </br> ') + 
        '<h2> </br> You got the following questions wrong. </br> </h2>' + 
        wrong.join(' </br> ');

print(html);
