Functional Programming in Scala Chapters 5 & 6
By John Vial
This talk will be a brief overview of Chapters 5 & 6 from Functional Programming in Scala.
In Chapter 5 we look at lazy evaluation and how this can allow you to operate over data structures of inifinite size.
In Chapter 6 we explore what it means to have state in a function program, and discover that it really just boils down to adding another parameter to the function and then applying an abstraction so that you can write functions that fit together without needing to know about the plumbing.
