Is what i did any worse than how he did it?

//All of the questions first then their answers var questionsAnswers = [ ['What is my name?', 'keno'], ['How old am I?', 'twenty'], ['Who is my girlfriend?', 'cindy'], ['How old is she?', 'nineteen'], ['What is my brothers name', 'jeremy'], ['How old is he?','seventeen'], ];

//prints to the html page function print(message) { document.write(message); }

//separates correct answers and wrong answers var correctList = '<ol>'; var wrongList = '<ol>';

//loops every question and adds to either correct or wrong for (var i = 0; i < questionsAnswers.length; i += 1){ var question = prompt(questionsAnswers[i][0]); if (question.toLowerCase() === questionsAnswers[i][1]){ correctList += '<li>' + questionsAnswers[i][0] + '</li>'; } else { wrongList += '<li>' + questionsAnswers[i][0] + '</li>'; } }

//end lists correctList += '</ol>'; wrongList += '</ol>';

//prints everything print("Correct Answers"); print(correctList); print("Wrong Answers"); print(wrongList);

Obviously it comes out different, but i just wanted to know if how he does it is a lot more efficient than how i did it.
