Ruby's philosophy is to provide more than one way to do the same thing. Faced with choice, we are left wondering which methods to use. In this talk, we will travel together on a refactoring journey. We will start from code that is easy to write but hard to read, and gradually advance to a level where the 4 C's of good code are satisfied: Correctness, Completeness, Clearness, and Compactness. On the way, we will learn new Ruby 2.4 methods (String#match?, MatchData#named_captures) and review old methods (Enumerable#find, Regexp#===) that are more powerful than they seem at a first glance.
