My code for Build a Quiz Challenge, Part 1.

I would like to say that so far the lessons on J/S are pretty awesome and it was made very well. I thought this challenge brought everything together that we learned so far.

Let me know what you guys think about my code.

var questionsCorrect = 'You got these questions correct:';
var questionsWrong = 'You got these questions wrong:';
var score = 0;

var answer; 
var question;

var quizQuestions = [
  [ 'Who killed Abraham Lincoln?', 'JOHN WILKES BOOTH' ],
  [ 'Which general crossed the Alps with Elephants?', 'HANNIBAL' ],
  [ 'Who lost at the Battle of Waterloo?', 'NAPOLEON' ],
  [ 'Which king separated the Church of England from the Roman Catholic Church?', 'HENRY VIII' ],
  [' Who first said "Veni, Vidi Vici?"', 'JULIUS CAESAR' ]
];

function takeQuiz ( quiz ) {
  var rightQuestion = '<ol>';
  var wrongQuestion = '<ol>';
  for ( var i = 0; i < quiz.length; i += 1) {
    question = prompt(quiz[i][0]);
    answer = quiz[i][1];
    if ( question.toUpperCase() === answer ) {
      score += 1
      rightQuestion += '<li>' + quiz[i][0] + '</li>';
    } else {
      wrongQuestion += '<li>' + quiz[i][0] + '</li>';
    }
  }
  rightQuestion += '</ol>';
  wrongQuestion += '</ol>';
  print( '<p>' + 'You got ' + score + ' question(s) right.' + '</p>' +
     '<h2>' + questionsCorrect + '</h2>' + rightQuestion + '<h2>' + questionsWrong + '</h2>' + wrongQuestion );  
}

function print(message) {
  document.write(message);
}

alert('Are you ready to take the History Quiz? Push OK to start');

takeQuiz( quizQuestions );

Thanks!
