Tell us what’s happening:

I can’t pass the test 11, 12, 13, and 14. While my code is producing what appears to be the correct output, the test is not accepting it. In addition, my code for the getRandomComputerChoice() is similar with getRandomQuestion(), and I have a feeling that it may have something to do with my problem. May I kindly ask for your advise please? TIA!

Your code so far

const questions = [
  {
    category: "Science",

function getRandomQuestion(arr) {
  const random = Math.floor(Math.random() * (arr.length - 0) + 0);
  return arr[random];
}

function getRandomComputerChoice(arr) {
  const random = Math.floor(Math.random() * (arr.length - 0) + 0);
  return arr[random];
}

function getResults(question, answer) {
  const randomQuestion = getRandomQuestion(question);
  answer = getRandomComputerChoice(randomQuestion.choices);

  if (answer === randomQuestion.answer) {
    return "The computer's choice is correct!";
  } else {
    return `The computer's choice is wrong. The correct answer is: ${randomQuestion.answer}`;
  }
}

console.log(getResults(questions));

  1. Your getResults function should take the question object as the first parameter and the computer’s choice as the second parameter.

If I check this console log:

function getResults(question, answer) {
  console.log(question, "****", answer)

It seems to output a lot more than just 1 question object.

console.log(getResults(questions));

Does this console log at the end of your code make sense?

getResults takes 2 arguments. The first argument should be a (1 single) question object, not an array of question objects, right?

Thank you for pointing out the output of my getResult() function, such a great hint! I am able now to pass the tests.
