Intro to FP in Scala: Exploring a Toolbox for Solving Problems - Part 3 of 6
summary
Series workshop dives into Scala type classes and shows concrete code that compiles: generic Functor → map lets a length function work over Option Task or Either, Apply → ap composes two F-wrapped args so a binary plus works, and Applicative → pure lifts plain values into F. Bind/flatMap sequences F-producing functions enabling for-comprehensions; applicative builders and the "scream" operator are shown as syntactic sugar. Examples use Option, Task, Either and Validation and compile in the live exercises.
