Is my code right to do the same in the future?

var question;
var answer;
var response;
var correct = 'This is the question(s) you got right' + '<ol>';
var wrong = 'This is the question(s) you got wrong' + '<ol>';

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

var questions = [
['When did the \'First world War\' begin? ', 1914],
['When did the \'Second World War\' begin? ', 1939],
['When did the \'Oqtomber Revolution\'  happened in Russia? ', 1917]
];


for (var i = 0; i < questions.length; i++) {
  question =  questions[i][0];
  answer = questions[i][1];
  response = parseInt(prompt(question));

  if ( response === answer ) {
    correct += '<li>' + question + '</li>';
  } else {
    wrong += '<li>' + question + '</li>';
  }
}
correct += '</ol> ';
wrong += '</ol>'; 

print(correct + wrong);

What kind of "future" requirements are you concerned about? I hope not a third world war!

You'll find that the more complex the program, the more ways there will be to write the code to do it. And 90% of "right" is achieving the intended results. The rest is making the code efficient, concise, and easily read and maintained. This code seems to do well in all those criteria, so if it also performs just like the example code, I'd say it's "right" for sure.

Good job! :+1:

Well, good. :wink: But can you elaborate a bit on the question?
