Building the quiz

I'm trying to build the quiz bit by bit. So far I've got a working for loop that goes through three questions. I'm stuck on keeping track of which are correct and which are incorrect. Here's my code so far:

var questions = [
    ["what is the number of states in USA?", "50"],
    ["what is the capital of NZ?", "Wellington"],
    ["What is 1 + 1", "2"]
]

var correct = 0
var incorrect = 0;

for (var i = 0; i < questions.length; i++) {
    var answer = prompt(questions[i][0]);
}
if(answer === questions) {
    correct += 1;

} else {
    incorrect +=1;

}

console.log(correct);
console.log(incorrect);


}

In the console, it says that

correct is 0 and incorrect is 1, no matter what i put for the answers

Hello, try putting your if-else statement inside the for loop, the way you have it right now, your only checking for the correct answer once, after the whole for loop finishes.

for (var i = 0; i < questions.length; i++) {
    var answer = prompt(questions[i][0]);

   if(answer === questions) {
       correct += 1;
    } else {
        incorrect +=1;
    }
} //end for loop

Good luck :)
