function getRandomQuestion(arr){
  return  arr[Math.floor(Math.random() * arr.length)];
}
function getRandomComputerChoice(arr){
 return arr.choices[Math.floor(Math.random() * arr.choices.length)];
}
function getResults(qu, choice){
 if(qu.answer === choice){
   return "The computer's choice is correct!";
 }else{
    return "The computer's choice is wrong. The correct answer is: " + qu.answer
 }
}
const getQuestion = getRandomQuestion(questions);
const getChoice = getRandomComputerChoice(getQuestion);
console.log(getQuestion);
console.log(getChoice);
console.log(getResults(getQuestion,getChoice))

not sure if this intended but if getresult test case passes with just passing the object n then .answer shouldnt the getchoice also pass with just passing the object like:

function getRandomComputerChoice(arr){
 return arr.choices[Math.floor(Math.random() * arr.choices.length)];
}

which result passing getchoies.choices instaed of just passing the obj as a whole

same with get result get result doesnt pass if i do

function getResults(qu, choice){
 if(qu === choice){
   return "The computer's choice is correct!";
 }else{
    return "The computer's choice is wrong. The correct answer is: " + qu
 }
}

then just passing .answer as a param like with getchoice
curious one solution passes for one test case but doesnt pass for the other
basically get choices requires to take question.choices as a param but cant pass question but get result can pass question but cant take question.answer as a param

sorry not sure if i made sense i kinda got confused midway typing the question

That depends on the function specification and tests. getResult is expected to take question object as first argument. On the other hand getRandomComputerChoice should take only the choices.

Because getResult is not using directly the getRandomComputerChoice, it can be tested in isolation. And getRandomComputerChoice implementation will not affect tests for getResult.

ya makes sense i was just wondering what found was just passing object then .property in the function got the same result when decided to just do .property as param instead
