Intro to FP in Scala: Exploring a Toolbox for Solving Problems - Part 2 of 6
summary
Workshop claims to turn Scala features into a concrete toolbox: live builds of a lazy future style Task, a type class for Show and Equals, and companion-object instances that enable implicit resolution. The session walks through the actual code: creating apply/ops helpers, implicit conversions, and tuple/Option/Either/Task adaptations, with compiler errors fixed on stage and exercises to implement Equals instances. The demos sometimes fail then compile after fixes, so expect real, incremental live coding and a working minimal toolkit at the end.
