Programming in Scala”

About this booklet
This booklet contains chapter notes, hints, answers to exercises, addenda, and errata for the book
Functional Programming in Scala¹ by Paul Chiusano and Rúnar Bjarnason. There is no original
material here, except for this brief introduction. This booklet is just a collection of material that is
freely available online².
Why make this?
Functional Programming in Scala is a book that relies heavily on exercises. This can make it difficult
to consume by reading rather than doing. Since the exercise answers, hints, and chapter notes are
all online, a number of people have expressed difficulty studying the book on a train, on flights, in
a classroom setting, or generally where there is no internet connection or where it’s inconvenient
to use a laptop. So what I’ve done is literally print all of that material in a single document, as a
companion for the book itself. Its purpose is to be convenient to use as a hardcopy, with an eBook
reader, a tablet, or a phone.
