Introduction

Welcome to your first lesson of Module 4! In this lesson, you’ll learn what classes are, how they work behind the scenes, and how to create an instance of one in code. Don’t worry if you don’t get the hang of everything at first. This is only the first lesson - but your professional bragging rights are within reach. By the end, you’ll be able to:

• Identify the purpose of a class.
• Describe how classes work in memory.
• Explain how to create an instance of a class.

It’s time to get started!
