What if I wanted my answers to be strings?

If I answer a question correctly, it does not register on the correctAnswers variable. No matter what I enter (in the case that the answers are strings instead of numbers) it prints on the page as zero correct. EDIT: in the case that the answers to the questions are strings, and not numbers.

Well, all the questions in the quiz are currently limited to ones that can be answered with a number. I just want to know what I would have to do to open it up so that someone could potentially write a question that requires a word answer instead of a number.

Do I just get rid of parseInt?

Hi Jeremy,

I'm not 100% sure what your issue is here. Maybe you could specify the question.

1. I changed the code a little to reflect that you can use strings as well.

2. If you want text to be accounted for in the user's answers - an approach would be to use an if statement that checks for the values that you want to have entered. to make it irrelevant how the user writes out the string (FIfty Fifty FIFTY fifty) I added in the .toLowerCase() Remark: I did not refactor so you can see the differences at glance - you can refactor (clean up) the code quite a bit.

3. I added some logging code that may help you as well: console.log( "response is: " + typeof response );

Keep in mind that this is a very minimalistic example and as soon as you are going bigger, you might want to change the code to use an array or objects to translate a lot of stuff to numbers.

<script>
  var 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;
  function print(message) {
    document.write(message);
  }
  for (var i = 0; i < questions.length; i += 1) {
    question = questions[i][0];
    answer = parseInt(questions[i][1]);
    response = prompt(question);
    console.log( "answer is: " + typeof answer );
    console.log( "response is: " + typeof response );
    if (response.toLowerCase() === "fifty") {
      response = "50";
    } else if (response.toLowerCase() === "seven") {
      response = "7";
    } else if (response.toLowerCase() === "six") {
      response = "6";
    }
    response = parseInt(response);
    if (response === answer) {
      correctAnswers += 1;
    }
  }
  html = "You got " + correctAnswers + " question(s) right."
  print(html);
  </script>```

I'm aware. I want the answer in the questions array to be a string, and I want the user to type that string into the prompt, and it to register as a correct answer.

I am not putting quotes in the prompt

Okay, cool. Should I still be processing the answers that are in fact integers differently? So if some answers are 50 and some are "Arizona", should they go through different pipelines? (sorry you've had to respond so many times)

If you want to use a mix of strings and integers as answers then use "==" instead of "===" (no parseInt required)

For example:

var questions = [
  ['How many states are in the United States?', '50'],
  ['How many continents are there?', 7]
];
var correctAnswers = 0;
var question;
var answer;
var response;

function print(message) {
  console.log(message);
}

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

html = "You got " + correctAnswers + " question(s) right."
print(html);

The following lines are the key:

 response = prompt(question);
  if (response == answer) {

Best Regards

Thanks for your help.
