Ruby Code Linting with RuboCop

In this episode, I go over using RuboCop, configuring it, driving out refactors with it, as well as my thoughts on how far to take it and when it's most useful. RuboCop is a Ruby linting tool that I've used at various places I've worked and in various projects. It can help catch issues before committing them, improve code quality and performance, and have a consistent style of code throughout a codebase. The `bundle gem` command has the option to include RuboCop by default, which I've been doing in this series. I adjust the config to suit my needs and refactor the code to appease some of the lint offenses.
