Doesn't show how many are right

var questions = [
['What color is the sky?', 'blue'],
['Whats the beginning of the Alphabet', 'a'],
['When its hot people usually like to eat what?', 'ice cream']  
];

var countA = 0;
var response;
var correct = [];
var wrong =[];


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

for ( var i = 0; i < questions.length; i += 1) {
  response = prompt(questions[i][0]);
  answer = questions[i][1];
    if ( response.toLowerCase() === answer.toLowerCase() ){
      countA += 1;
      correct.push(questions[i][0]);
     } else {
      wrong.push(questions[i][0]);
     }
}


html = 'You got ' + countA + 'question(s) right.';

You need to make use of the print() function in your code. I which case, you need to add

print( html );

at the end.

And declare the variable html before assigning a value to it. Or just print the concatenated string instead of assigning it to a variable first.

Hello, You need to target an element on your html page, and update it's innerHTML property. eg something along the lines of:

var mydiv = document.getElementById('myDiv');
mydiv.innerHTML =  'You got ' + countA + 'question(s) right.';
