Tell us what’s happening:

I felt like it’s already fulfill its goal. However, seems like I had miss somethings? I know that the fact that I can’t just put function inside the function params without declaring it as a variable. So, do anyone have any Idea?

Your code so far

const questions = [{
  category: "Easy",
  question: "What is 1+1?",
  choices: ["2","Two","Window"],
  answer:"2"
},{
  category: "Medium",
  question: "Why is sun rising from the east?",
  choices: ["Orbit","It is what it is","idk"],
  answer:"Orbit"
},{
  category: "Hard",
  question: "Why is duck mostly have darker feather?",
  choices: ["Water","Sun","idk"],
  answer:"Sun"
},{
  category: "HARDCORE",
  question: "Why is 727 became an osu! culture?",
  choices: ["Cookiezi","BTMC said Cookiezi","Cookiezee"],
  answer:"Cookiezi"
},{
  category: "KASAIIIII",
  question: "ASAHI???",
  choices: ["PULU","ASAHI","TENG"],
  answer:"ASAHI"
}];

function getRandomQuestion(arr){
  return arr[(Math.ceil(Math.random()*arr.length-1))];
};

function getRandomComputerChoice(arr){
  return arr.choices[Math.ceil(Math.random()*arr.choices.length-1)];
} 

function getResults(arr, randAns){
  if (randAns === arr.answer){
    return `The computer's choice is correct!`;
  } else if (randAns !== arr.answer) {
    return `The computer's choice is wrong. The correct answer is: ${selectedQuestion.answer}.`;
  };
};

const selectedQuestion = getRandomQuestion(questions);
const computerChoice = getRandomComputerChoice(selectedQuestion);

console.log(`Question: ${selectedQuestion.question}`);
console.log(`Computer picked: ${computerChoice}`);
console.log(getResults(selectedQuestion, computerChoice));

hello @juliusechndr welcome to the forum!

If arr is an array, what should you get if you log arr.choices? Currently your function is expecting an object with a choices property.

You should remove the last full-stop here.

},{
  category: "HARDCORE",
  question: "Why is 727 became an osu! culture?",
  choices: ["Cookiezi","BTMC said Cookiezi","Cookiezee"],
  answer:"Cookiezi"
},{
  category: "KASAIIIII",
  question: "ASAHI???",
  choices: ["PULU","ASAHI","TENG"],
  answer:"ASAHI"
}];

function getRandomQuestion(arr){
  return arr[(Math.ceil(Math.random()*arr.length-1))];
};

const randomQuestion = getRandomQuestion(questions);

function getRandomComputerChoice(arr=randomQuestion){
  return arr.choices[Math.ceil(Math.random()*arr.choices.length-1)];
};

function getResults(arr, randAns){
  if (randAns === arr.answer){
    return `The computer's choice is correct!`;
  } else if (randAns !== arr.answer) {
    return `The computer's choice is wrong. The correct answer is: ${selectedQuestion.answer}`;
  };
};

const selectedQuestion = getRandomQuestion(questions);
const computerChoice = getRandomComputerChoice(selectedQuestion);

console.log(`Question: ${selectedQuestion.question}`);
console.log(`Computer picked: ${computerChoice}`);
console.log(getResults(selectedQuestion, computerChoice));

So here, I’ve store the random question an variable and it seems to fix a check. Now I miss three checks. I don’t really understand what do I miss here. I also remove that full-stop on my else if, thank you for your notes.
