JavaScript Object-Oriented JavaScript (2015) Practice Project Project Overview

Trouble pushing to Array.

With the code below my array is empty. I am unable to figure out why.

// Question.js

function Question(question) {
    this.question = question;
    return question;

Question.prototype.toHTML = function(question) {
    var htmlString = question;
    return htmlString;

// Quiz.js

function Quiz() {
    this.questions = [];
    this.currentQuestionIndex = 0;

// Adds new question to array
Quiz.prototype.add = function(newQuestion) {

// App.js

// Create quiz
var quiz = new Quiz();

// Create Questions
var question1 = new Question('What is 2 + 2?');
var question2 = new Question('What is the capitol of the United States?');

// Add Questions

Why do you think it's empty?

It's empty where you have the console.log statement but I don't think it's empty by the end of the code.

Try running console.log(quiz.questions); as your last line and you should see that it's populated.

Thanks! It isn't empty. You also answered the question I asked before this.
