About the Book
In this book you will learn about functional and object-oriented aspects of Scala. You will learn how to write expressive, intent-revealing code using pattern matching, functional sequence processing and for comprehensions, and how to design data types that enforce their business invariants in a functional way, without throwing exceptions. You will get a first glimpse at Scala's powerful type system and how to abstract over concrete types, and you will learn all there is to know about working with Option, Scala's approach at avoiding the million dollar mistake of null references.
