In this video we cover Ruby Koans, specifically about class methods.
If you want to learn to program, the Ruby programming language is one of the best to start with in my opinion. Ruby Koans is a way of learning in which you work through a process of getting tests to pass. At the start you have ~300 failing tests which you address one at a time. With each step, you learn about the Ruby programming language and how to operate as a software maker.
