In this chapter, we will start organizing data in blueprints that generate objects. We will protect and hide data in each of the three covered programming languages: Python, JavaScript, and C#. We will:
Understand the different members of a class
Learn the difference between mutability and immutability
Customize methods and fields to protect them against undesired access
Work with access modifiers, naming conventions, and properties
Customize getter and setter methods
Create properties with getters and setters in Python, C#, and JavaScript
