Chapter 5. Object-Oriented Programming
In this chapter, we cover the most widely used programming paradigm today: object-oriented programming. Mastering object-oriented programming is crucial for taking advantage of the existing frameworks and libraries available on .NET, as well as writing F# code that can be integrated into those libraries.
Programming with Objects
Software systems are the some of the most complex things created by man. Consider your typical .NET program: thousands if not millions of lines of source code, transformed into some intermediate language by compilers, then compiled again to machine code via a JITer, which then executes on a processor. Knowing the details about how each step works is just too much to handle.
Rather than sweating all the details of a program, object-oriented programming enables you to organize batches of code into conceptual objects, so that you can limit your interactions with code to small and well-defined interfaces.
The Benefits of OOP
There are several benefits to object-oriented programming:
- Encourages code reuse
By encapsulating your code into objects, it can be reused, which ultimately saves time and enhances productivity.
- Tame complexity
Rather than dealing with myriad individual functions and global variables, OOP allows you to deal with one item at a time. Any mutable state is scoped to just the object.
- Specialization through inheritance
Using polymorphism, you can write code that deals with a base type of object, and still accepts any ...
