Summary
In this chapter, we explored the various ways that object-oriented programming techniques such as inheritance, encapsulation, and polymorphism can be used to refactor code toward more maintainable forms.
Refactoring can be a complex endeavor, and yet so many of the fundamental concepts of object-oriented programming can come together to build elegant, flexible, and maintainable solutions.
This concludes Part 1 of the book. In the next part of the book, we’ll look at how testing can give you the safety and freedom needed to safely refactor your code and move forward with confidence that your changes have improved the application without breaking anything.
