I realized that the questions array is an object after using the typeof method.
I’ve tried writing the objects in side the array directly,but test 1-8 doesn’t pass on doing this.
how can I go about this?
Your code so far
const questions = []
const object1 ={
category: "Mathematics",
question: "solve for x in : x^2 +8x + 6 = 0?",
choices: ["-3 twice","2 and 3","-4 twice"],
answer: "-4 twice"
}
const object2 ={
category: "chemistry",
question: "what gas law state : the sum of the partial pressure of a gas is equal to the pressure of the gas?",
choices: ["avogadro","gay lussac","max carl"],
answer: "gay lussac"
}
const object3 ={
category: "physics",
question: "A machine carry a load of a 50N through a height of 20m in 10minutes. if the machine power is limited to 2Watts.find the efficiency of the machine?",
choices: ["0.967","0.7889","0.833"],
answer: "0.833"
}
const object4 ={
category: "History",
question: "how many are the ulul azm among the prophets of Allah?",
choices: ["7","6","5"],
answer: "5"
}
const object5 ={
category: "fiqh",
question: "which of the following vitiates the ablution of the one that wants to offer salah?",
choices: ["food","urination","talking"],
answer: "urination"
}
questions.push(object1,object2,object3,object4,object5);
function getRandomQuestion(questions){
let randomNum = Math.round(Math.random()*questions.length)
return questions[randomNum].question
}
getRandomQuestion();

Yes, but how do I go about it ?
Because I tried putting the objects in the array directly but all the tests from 1 to 8 is not passing.
So the .length property is not working for the array.
test 9,11 and 13 didn’t pass despite getting the right output in the console.
how do I solve this ?

You can see randomChoice is faded out because it’s not referenced at all within the function. Isn’t it odd for a function not to use the parameters it’s defined to use?
