Chapter 2. Classes and Instances

In this chapter, we will start generating blueprints to create objects in each of the three programming languages: Python, JavaScript, and C#. We will:

• Understand the differences between classes, prototypes, and instances in object-oriented programming
• Learn an object's lifecycle and how object constructors and destructors work
• Declare classes in Python and C# and use workarounds to have a similar feature in JavaScript
• Customize the process that takes place when you create instances in Python, C#, and JavaScript
• Customize the process that takes place when you destroy instances in Python, C#, and JavaScript
• Create different types of objects in Python, C#, and JavaScript
