Putting together all the pieces of the object-oriented puzzle

In Chapter 1, Objects Everywhere, you learned how to recognize objects from real-life situations. We understood that working with objects makes it easier to write code that is easier to understand and reuse. However, Python, C#, and JavaScript have different object-oriented approaches, and each programming language provides different features that allow you to generate and organize blueprints for objects. If we have the same goals for an application, we will end up with completely different object-oriented approaches in Python, C#, and JavaScript. It is not possible to use the same approach in these three languages.

In Chapter 2, Classes and Instances, you learned that in Python and C#, classes are the blueprints or building blocks that we can use to generate instances. Both the programming languages allow you to customize constructors and destructors. JavaScript has a different approach. We can easily create objects in JavaScript...
