response = prompt(question); is not storing users input. Instead it stores the but question string from the array.

Question

I have followed this tutorial code exactly and keep running into the same error. The response = prompt(question);   is storing the original question string from the quizQuestions array rather than what the users typed in answer is, therefore :
if (response === answer) 
will always return false.
 The Also had this problem when trying to code prior to watching the answer video... What am I doing wrong? 
// My Code  
var quizQuestions = [
  [ 'What is the color of the sun?' , 'Yellow' ] ,
  [ 'What is the color of the grass?' , 'Green' ] ,
  [ 'What is the color of the sky?' , 'Blue'] ,
]
  var correctAnswers = 0;
  var question;
  var answer;
  var response;
  var html;
function print(message) {
  document.write(message);
}
// Ask the questions
  for (var i = 0; i < quizQuestions.length; i += 1) {
    question = quizQuestions[i][0];
    answer = quizQuestions[i][1];
    response = prompt(question);
    response = question.toLowerCase();
  if (response === answer) {
    correctAnswers += 1;
  }
}
html = "You got " + correctAnswers + " question(s) correct.";
print(html);
// You can see it is incorrect by console.log response or by getting the answers right and noting that they are not added to the correctAnswer count.

The prompt isn't the issue, but the line after it is replacing the result with the question:
js
    response = prompt(question);        // this gets the user's answer into "response" 
    response = question.toLowerCase();  // this replaces "response" with question (in lower case)

Perhaps you intended to convert the reponse to lower case.  You can do that on the same line:
js
    response = prompt(question).toLowerCase();

Also, to format posted code as shown here, use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrowheadingdown:
