Tell us what’s happening:

Test case 8 is not passing. The function getRandomQuestion does return a random object but, it still won’t pass.

Your code so far

let questions = [];

let question1 = {
  category: 'Animals',
  question: 'What kind of animal has a meat only diet?',
  choices: ["Omnivore", "Meat-Eater", "Carnivore"],
  answer: "Carnivore",
}

let question2 = {
  category: 'Automotive',
  question: "What type of engines do gasoline vehicles have?",
  choices: ["Inline-4", "Combustible-engine", "Combustion-engine"],
  answer: "Combustion-engine",
}

let question3 = {
  category: 'Coding',
  question: "What is the best language to learn?",
  choices: ["JavaScript", "Pytherium", "SEA++"],
  answer: "JavaScript",
}

let question4 = {
  category: 'Scripture',
  question: "Who is Jesus?",
  choices: ["A cool dude", "Prophet", "the Word"],
  answer: 'the Word',
}

let question5 = {
  category: 'Health',
  question: "On average, how many hours of sleeps is recommended?",
  choices: ["10 hours", "8 hours", "What is sleep?"],
  answer: "8 hours",
}

questions.push(question1, question2, question3, question4, question5)

function getRandomQuestion(questions) {
  return questions && questions.length !== 0 ? questions[Math.floor(Math.random() * questions.length)] : null;
};

function getRandomComputerChoice(choices) {
  return choices && choices.length !== 0 ? choices[Math.floor(Math.random() * (choices.length))] : null;
};

function getResults(question, choice) {
  return choice == question.answer ? "The computer's choice is correct!" : `The computer's choice is wrong. The correct answer is: ${question.answer}`
}

let question = getRandomQuestion(questions);
let choice = getRandomComputerChoice(question.choices);
let result = getResults(question, choice);

console.log(question);
console.log(choice);
console.log(result);

you have created the function that takes an argument, but the expected is that the function doesn’t take an argument and refer to the global object

Thanks so much, should of thought of/tried that.

4

can I give you some feedback on this pattern?
this is a legacy way of doing, in modern code you should use optional chaining

I appreciate the feedback. Thank you for the article. I updated the code as well.
