Array of answers?

I am just starting my challenge.. and as I am going through the requirements, I am struck by this question.. While asking our 5 questions. Should we have a list of the correct answers to check user input against? or am I just over thinking a very simple step and just use prompt and check against the answer directly in if?? say 

var questionOne = prompt("is yes or no"); 
if (questionOne === "yes") { 
correctAnswers++;
}

Taking it further, you could use an array of objects to store your questions and answers:

//Variables

var score = 0;
var questions = [
   {
      text: "What is the abbreviation of Kentucky?",
      answer: "KY"
   },
   {
      text: "Is cheese delicious?",
      answer: "NO"
   },
   {
      text: "What type of animal has spots and a long neck?",
      answer: "GIRAFFE"
   }
];

//code to run

for(i=0;i<questions.length;i++){

   var current_question = questions[i];
   var guess = prompt(current_question.text);

   if(guess.toUpperCase() == current_question.answer){
      score += 1;
   }
}

Rich's answer is much cleaner and complete, even if he's a cheese-hating heretic!

See that's where I was originally going in my head but then I started second guessing if I actually could do it that way then I started thinking this is supposed to be "beginner" and using objects doesn't come until later. I'm really good at doing the opposite of what we are supposed to do when breaking down problems into smaller problems I tend to go to far or over complicate things... This for example.

But rich your answer is exactly where my mind was going.

Hi Anthony,

I'm not familiar with what the challenge requires, but from a functional standpoint you could go about it as you have written, by checking if the user's answer is equal to a specific value.

Another way to do it would be like you were thinking and have an array of answers, with each index in the questions array matching the index in the answers array:

 var questions = ["What is the abbreviation of Kentucky?", "Is cheese delicious?", "What type of animal has spots and a long neck?"];
 var answers = ["KY", "Yes", "Giraffe"];
 var correctAnswers = 0;

 for (var i=0; i<questions.length;  i++) {
   var userAnswer = prompt(questions[i]);
       if (userAnswer === answers[i]) {
             correctAnswers++;
        } 
 }
