};

my program work , but the test 11 and 12 not passed. please help what is the problem

23

what is test 11 asking from you?

24

The problem is that the instructions ask you to pass the selected question object to the function but instead you are passing the answer property.

25 
function getResults(pcChoice,answer) {
   return pcChoice == answer? "The computer's choice is correct!" : `The computer's choice is wrong. The correct answer is: ${answer}`};
//FUNCTION CALL
let gRandomQuestion = getRandomQuestion(questions);
let computerChoice = getRandomComputerChoice(gRandomQuestion.choices);
let result=getResults(computerChoice,gRandomQuestion.answer);
console.log(result);

Do you mean like this?

26

Is this the question object or the answer property?

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

27

the answer property. if we send the question object us argument of getResults function i edited the code us bellow. but stil not passed.

function getResults(pcChoice,gRandomQuestion) {
    let answer=gRandomQuestion.answer;
   return pcChoice == answer? "The computer's choice is correct!" : `The computer's choice is wrong. The correct answer is: ${answer}`};
//FUNCTION CALL
let gRandomQuestion = getRandomQuestion(questions);
let computerChoice = getRandomComputerChoice(gRandomQuestion.choices);
let result=getResults(computerChoice,gRandomQuestion);
console.log(result);
28

I hope you can guess my next question.

Is gRandomQuestion a question object? How can you check?

Does the getRandomQuestion return an object?

To be clear of the difference, this is an object:

{
 category:"color? ", 
 question:"what is your favorite color?",
 choices:["blue","pink","green"],
 answer:"green",
}

This is a property:

answer:"green"
29

yes, gRandomQuestion is an object of questions array that is returned from
getRandomQuestion functions.
getRandomQuestion return and object.

30

Ok can you show me why? I disagree with you, so can you prove it?

EDIT: Ok I see you’ve updated your code, it looks like getRandomQuestion should be returning an object. :+1:

Can you post your full code update with the new getResults() function as well, so I can see it all together?

31

This is an annoying one:

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

function getResults(pcChoice,gRandomQuestion) {

Your function takes the choice, and then the question.
