My Solution

function print(message) {
  document.write(message);
}
// Questions array
var questions = [
  ['What is the capital of BG?', 'sofia'],
  ['What is the capital of NO?', 'oslo'],
  ['What is the capital of SE?', 'stockholm']
];

// Setting up HTML output and vars to store correct/wrong answers
var toHTML = "<ol>";
var correct = 0;
var wrong = 0;

// loop
for (i = 0; i<questions.length; i++) {
  if (prompt(questions[i][0]).toLowerCase() === questions[i][1]) {
    toHTML += "<li>" + "Your answer to: " + "\"" + questions[i][0] + "\"" + " was correct!" + "</li>";
    correct++;
  } else {
      toHTML += "<li>" + "Your answer to: " + "\"" + questions[i][0] + "\"" + " was wrong!" + "</li>";
      wrong++;
  }
}
// completing the output for HTML
toHTML += "</ol>" + "<p>" + "You got " + correct + " answer(s) right and " + wrong + " answer(s) wrong";
print(toHTML);
