Tell us what’s happening:

I cannot pass the ‘11. Your getResult function should take the question object as the first parameter and the computer’s choice as the second parameter.’ and ‘12. If the computer choice matches the answer. The getResults should return “The computer’s choice is correct!”’. Please help.

Your code so far

const questions = [
  {
    category: "Culinary Arts",
    question: "Which of these ingredients is essential for making a traditional Filipino 'caramel' or 'yema' icing?",
    choices: ["Whipping Cream", "Condensed Milk", "Cream Cheese"],
    answer: "Condensed Milk"

Hi @palenciajp22,

What type of data structure is randomQuestion? (Look at your logs)

Can you expect randomQuestion to ever equal computerChoice?

Happy coding!

Pardon. What do you mean data structure? is it not ‘object’?

I expect randomQuestion to not equal computerchoice. When I do change it to “===” . All of this “Failed:11. Your getResults function should take the question object as the first parameter and the computer’s choice as the second parameter.

  • Failed:12. If the computer choice matches the answer, getResults should return The computer's choice is correct!

  • Passed:13. If the computer choice doesn’t match the answer, getResults should return The computer's choice is wrong. The correct answer is: <correct-answer>, where <correct-answer> is the value of the correct answer to the chosen question.

  • Passed:14. Your getResults function should use exact equality comparison, not substring matching.” is wrong. But when I do “!==” only 11 and12 were wrong.

Yes, randomQuestion is an object. Your comparison operator is correct, but will a question object ever be equal to a question choice? What should you compare instead?

You’re very close, the issue is just in your comparison logic.

In your getResults function, you are comparing the entire randomQuestion object with computerChoice, which will always be different. Instead, you should compare the correct answer inside the question object with the computer’s choice.

Try updating your function like this:

The key point is:
Compare computerChoice with question.answer, not the whole object

Once you fix that, both tests 11 and 12 should pass .
I hope it helps
