Object oriented programming and Ruby go hand in hand. This lesson, we'll learn how to define classes and create instances of them to organize our code.

Loops allow you to run code multiple times. This is handy when you need to process a group of items one at a time until the entire group is finished. We'll also learn about Ruby blocks to define the set of operations.

So far, our project has been a single line of operation. We can refactor this to use methods to reuse code in various ways.

A method or function is a way to define a group of code that can be used repeatedly. We'll learn how to define methods in our Ruby code and then use them multiple times.
