Some play with the Ruby programming language while working through the book, Seven Languages in Seven Weeks, by Bruce A. Tate.
The code in this repo is based on the self-study exercises from each of the three days covered in the book. A few extra niceties have been added to each exercise to explore the language further.
Ruby version 2.5 has been used whereas the book recommends 1.8. It should not matter.
Make sure to have Ruby installed. RVM is great for managing versions.
Then for example run ruby day1/1.rb.
