Is this too messy?

//vars
var questions = [
  [ 'What is the name of the program we are currently learning?', 'javascript'],
  [ 'What is the name of the website we are using?', 'treehouse'],
  [ 'What is 2+2?', 4]
];
var questionHTML;
var correctAnswers = 0;
var wrongAnswers = 0;

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

//question loop
for ( var i = 0; i < questions.length; i += 1) {
  var questionsAnswer = prompt( questions[i][0] );
    if( questionsAnswer.toLowerCase() === questions[i][1] || parseInt(questionsAnswer) === questions[i][1] ) {
      alert('Correct!');
      correctAnswers += 1;
  } else {
    alert('Wrong!');
    wrongAnswers += 1;
  }
}

questionHTML = 'You have answered ' + correctAnswers + ' questions correctly and ' + wrongAnswers + ' questions incorrectly!';
print(questionHTML);
