},
{
 category:"sports?", 
 question:"What is your favorite sport?",
 choices:["football", "volleyball","swimming"],
 answer:"volleyball",
}

];
let random = Math.floor(Math.random() * questions.length);
function getRandomQuestion(questions) {
    let randomQuestion = random;
    return questions[randomQuestion].question;
};
//FUNCTION CALL
let gRandomQuestion = getRandomQuestion(questions);
let finduserAnswer = questions.find(user => user.question === gRandomQuestion);
let userAnswer = finduserAnswer.answer;


function getRandomComputerChoice(choices) { 
   return choices[random];
};
//FUNCTION CALL
let computerChoice = getRandomComputerChoice(questions[random].choices);

//result Function
function getResults() {
    if (computerChoice == userAnswer) {
        return "The computer's choice is correct!";
    }
    else {
        return `The computer's choice is wrong. The correct answer is: ${userAnswer}.}`;
    }
};
console.log(getResults());

I am not sure I understand, whad do you think is the issue?

3

what is the problem of my code?

4

check the output string

if you don’t see anything wrong double check it, triple check it

5

i checked it, but test number 8,11,12 not passed

6

And you are printing to the console The computer's choice is wrong. The correct answer is: volleyball.} are you sure there is anything wrong with this string? isn’t there something extra?

7

. and } are extra, but still not work

8

now that you have removed that, let’s take a look at the getRandomQuestion function.

If you call that function multiple times, do you expect to get different questions or always the same one? ahve you tried calling it multiple times?

let random = Math.floor(Math.random() * questions.length);
function getRandomQuestion(questions) {
    let randomQuestion = random;
    return questions[randomQuestion].question;
};

console.log(getRandomQuestion(questions));
console.log(getRandomQuestion(questions));
console.log(getRandomQuestion(questions));

I made some changes, but still not passed .

11 
function getRandomQuestion(questions) {
    let randomQuestion = Math.floor(Math.random() * questions.length);
    return questions[randomQuestion];
};

//FUNCTION CALL
let gRandomQuestion = getRandomQuestion(questions);

function getRandomComputerChoice(gRandomQuestion) {
    let random = Math.floor(Math.random() * gRandomQuestion.choices.length);
    return gRandomQuestion.choices[random];
};
//FUNCTION CALL
let computerChoice = getRandomComputerChoice(gRandomQuestion);

let rightAnswer = gRandomQuestion.answer;
function getResults() {
    if (computerChoice === rightAnswer) {
        return "The computer's choice is correct!";
    }
    else {
        return `The computer's choice is wrong. The correct answer is: ${rightAnswer}`;

Did you do this part?

You should have a function named getResults that takes the selected question object and the computer choice as its parameters

item 9 from the user stories

15 
function getResults(pcChoice,truAnswer) {

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

console.log(getResults(computerChoice,rightAnswer));
