Whenever I run this code it always returns with 0 questions right

Everything works except the 'print(questionsRight); ' bit... It always prints 0 onto the page. Here is the code:

var questionsRight = 0
var response;
var answer;
function print(message) {
  document.write(message);
}

var quizQuestions = [
  [ 'In a game of quidditch, is a seeker the one that looks for the golden snitch?', 'YES'],
  [ 'What is the animal of Gryffindor?', 'LION'],
  ["What is the first name of Harry Potter's son?", 'ALBUS']
];

for ( var i=0; i<3; i+=1 ) {
  response = prompt( quizQuestions[i][0] );
  answer = quizQuestions[i][1];
if( response.toUpperCase === answer){
    questionsRight +=1;
  } else {
    questionsRight +=0;
  };

} 

print(questionsRight);

:point_right: To call a method, you must include parentheses "()" after the method name.

So to make a string upper case, you attach ".toUpperCase()" to it. Without the parentheses, you are only naming the method, but not calling it.
