Questions & answers are showing up as [object Object] when ran, program runs properly though?!

code = https://w.trhou.se/0jmoorm1gu

Hi all, i'm trying to replicate the quiz from lesson JavaScript Loops, Arrays and Objects - Build a Quiz Challenge, Part 2 but im using an Object instead of a Two-Dimension Array for the questions / answers.. The code is running properly except when given the prompt for the question, it's showing [object Object] instead of the actual question, along with after the quiz when it displays the correct questions / answers in the document. What am I doing wrong here?

Hi Hunter,

You are missing a very important portion when working with objects. Here is your current code and the missing piece.

for (var i = 0; i < questions.length; i += 1) {
  question = questions[i];
  response = parseInt(prompt(question));
  if (response === question.answer) {
    correctAnswers += 1;
    alert("That's correct!");
    correct.push(question);
  } else {
    wrong.push(question);
  } 
}

/* ========================
It should be like this below
======================== */

for (var i = 0; i < questions.length; i += 1) {
  question = questions[i].question; // you forgot to request the question from the object
  response = parseInt(prompt(question));
  console.log(response, typeof response)
  if (response === questions[i].answer) { // same here to compare response and answer
    correctAnswers += 1;
    alert("That's correct!");
    correct.push(question);
  } else {
    wrong.push(question);
  }
}

I hope this helps.

Hey Hunter, I had a typo in my original answer and have since edited it. Copy my answer again and try it out. That should have fixed your issue.

Let me know if that is not the case.

You are awesome Chyno, thank you very much! Good eye on that typo, that made all the difference :) . . It can be confusing naming objects / variables so similarly lol.
