Help: I can't figure out why the alert "Sorry. That is incorrect" pops up even if I enter the correct answer.

Please look at my code and tell me what I'm doing wrong. I don't understand how to approach this challenge at all. I haven't even attempted to do the next step and print the correct answers to the page.

function print(message) {
  document.write(message);
}

var questions = [
  ['What is 2+2?', '4'],
  ['What is the capital of Spain?', 'Madrid'],
  ['Who was the 44th president?', 'Barack Obama']
];
var quiz;
var answer = ' ';


for (var i = 0; i < questions.length; i += 1) {
  var quiz = prompt(questions[i][0]);
  if ( answer === questions[i][1] ) {
      prompt('That is correct!');
  } else {
    if ( answer !== questions[i][1]) {
      alert('Sorry. That is incorrect.');
    };
  }
};

  1. Change var quiz = prompt(questions[i][0]); to answer = prompt(questions[i][0]); First, you've already declared the variable so var is not needed. Second, more importantly, the answers to the questions should be stored in the answer variable not the quiz variable. Right now, the answer variable will always be an empty string; therefore, you will always be alerted Sorry. That is incorrect.
  2. if ( answer !== questions[i][1]) { is unnecessary; just else is enough.

Edit: I've just noticed that you are using the prompt method if the answer is correct, not alert.
