Tell us what’s happening:

How do I progress further, please help. Give me some hint, guide me little bit. Also in my getComputerChoice function I am unable to use parameter

Your code so far

const questions = [
  {
    category: "PCo",
    question: "fav color ?",
    choices: ['Red', 'Black', 'Both'],
    answer: 'Red'
  },
  {
    category: "PCa",
    question: "Fav car ?",
    choices: ['Honda', 'BMW', 'both'],
    answer: 'Honda'
  },
  {
    category: "PB",
    question: "Fav brand ?",
    choices: ['Amazon', 'Google', 'Both'],
    answer: 'Both'
  },
  {
    category: "PF",
    question: "Fav fruit ?",
    choices: ['Apple', 'Grapes', 'Mango'],
    answer: 'Mango'
  },
  {
    category: "PH",
    question: "fav hobby ?",
    choices: ['Singing', 'Coding', 'Both'],
    answer: 'Both'
  }
];

let randomNum = Math.floor(Math.random() * 5);

let anotherRandomNum = Math.floor(Math.random() * 3);

function getRandomQuestion() {
  return questions[randomNum].question
}

function getRandomComputerChoice() {
  return questions[randomNum].choices[anotherRandomNum];
}

function getResults() {}

console.log(getRandomQuestion())
console.log(getRandomComputerChoice())

Don’t make the random assignment globally.

Write the logic within the functions. Parameters Geos within the () braces of function definition.

but then how do I get same answer choices of that same question. I will show you an example.

const questions = [
  {
    category: "PCo",
    question: "fav color ?",
    choices: ['Red', 'Black', 'Both'],
    answer: 'Red'
  },
  {
    category: "PCa",
    question: "Fav car ?",
    choices: ['Honda', 'BMW', 'both'],
    answer: 'Honda'
  },
  {
    category: "PB",
    question: "Fav brand ?",
    choices: ['Amazon', 'Google', 'Both'],
    answer: 'Both'
  },
  {
    category: "PF",
    question: "Fav fruit ?",
    choices: ['Apple', 'Grapes', 'Mango'],
    answer: 'Mango'
  },
  {
    category: "PH",
    question: "fav hobby ?",
    choices: ['Singing', 'Coding', 'Both'],
    answer: 'Both'
  }
];


function getRandomQuestion() {
  let randomNum = Math.floor(Math.random() * 5);
  return questions[randomNum].question
}

function getRandomComputerChoice() {
 let randomNum = Math.floor(Math.random() * 5);
  let anotherRandomNum = Math.floor(Math.random() * 3);
  return questions[randomNum].choices[anotherRandomNum];
}

function getResults() {}

console.log(getRandomQuestion())
console.log(getRandomComputerChoice())

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

getRandomQuestion should return an object, not a string

7

Yes, you should return a random object form the questions array.
Also you need to return rendom choices from the choices array.

Hint: to get a random index of an array, you need to floor the array length and return that index in the array.

8

but how ? 4th point in lab says - The question key should have the value of a string representing a question.

it is a string, how do I make it return object ?

9

but the question key is inside… what?

10

inside an object inside questions array

11

so you have an object you can return

12

yes, but I am not able to think how.
Can you please guide me step by step ?

13

here, are you retrieving the question from what?

14

from questions array

15

but inside the array what do you have?

16

5 objects
so, I am retrieving the question from objects elements inside questions array

17

so you are getting the question from one specific object, right? what if you just don’t get the question from the object?

18

I just get an random object

19

and is there something wrong with that?

20

No, i can’t think what is wrong and why it is wrong

21

try it then, try it in the code
