My solution to Challenge 1 Building a Quiz

Um I am so sure this is not the way to do it, but it "works" so, thought?

var gotRight = 0;
var gotWrong = 0;
var result = "";

var questions = [];
questions.push(["Who sang 'When a Man Loves a Woman'?", "percy sledge"]);
questions.push(["Who sang 'Sitting on the Dock of the Bay'?", "otis redding"]);
questions.push(["Who sang 'Sinnerman", "nina simone"]);

var answers = [];
answers.push(prompt(questions[0][0]).toLowerCase());
answers.push(prompt(questions[1][0]).toLowerCase());
answers.push(prompt(questions[2][0]).toLowerCase());

for (var i = 0; i < questions.length; i++) {
  if ((answers[i]) === questions[i][1]) {
      gotRight += 1;

      }else {
      gotWrong += 1
      }
}

result = "You got " + gotRight + " right, and " + gotWrong + " wrong.";

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

Why is it "not the way"? It looks really good to me! :+1:

One minor suggestion: prompt and save the answer inside the loop so it only takes one line instead of three.
