Goal of This Chapter

The goal of this chapter is to familiarize you with the key concepts of object orientation, when to use it, and when to avoid it.

It does not teach object orientation in a specific language, but focuses on the rationale of using it, as well as the general anatomy of object orientation. Not all languages have the same object-oriented abilities, and it will be up to you to decide which language suits you best and then take these principles and implement them to the extent that language implements it.
