RubyConf Mini 2022: Teaching Ruby to Count by Joël Quenneville

Ruby has some of the best tooling in the business for working with iteration and data series. By leveraging its full power, you can build delightful interfaces for your objects. In this case-study based presentation, we’ll explore a variety of problems such as composing Enumerable methods, generating a series of custom objects, and how to provide a clean interface for a collection with multiple valid traversal orders. Beyond just the beloved Enumerable module, this talk will take you into the world of Enumerators and Ranges and equip you to write objects that bring joy to your teammates.
