In this chapter, you learned how to extend built-in classes with additional methods (like adding another string method or integer method), and how to change existing methods (by simply defining a method of the same name as the one you want to change). You then learned how to make your own classes, complete with instance variables and an initialize method. Finally, you learned how to hide some methods from the rest of your code by making them private.

Now that you’ve had a chance to practice by creating some classes of your own, you know even more Ruby. In the next chapter, you’ll turn your gaze outward, and learn how to use Ruby (and JSON) to talk to other programs over the Internet.
