| Welcome back! [Last time]({% link _posts/2023-04-24-concerns-in-ruby-part-1.md %}), we discussed the basics of concerns in Ruby and saw a few examples of how to use them to share code across otherwise-unrelated sets of classes. We then took a detour with the goal of understanding, not just what concerns are, but also how to use them well. As part of that detour, we defined good software as, "software that can change inexpensively." We said that the concept of "inexpensive" encompassed a myriad of factors including time, money, and effort. |
