Abstract
We have learned a lot about the Ruby programming language itself in the previous chapters along with its syntax and type characteristics. In this chapter we begin to look at "reusable code," the ability to write a snippet of code that can be used multiple times during our application. This is sometimes known as the D.R.Y. (Don't Repeat Yourself) principle.
