Track Correct answers and wrong answers.

For arrays challengevar 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 html; var correct=[]; var wrong=[];

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{wrong.push(question);}
