About the Book
In this book you will learn more about algebraic data types and about pattern matching, and you will get insights into functional ways of error handling. You will learn about essential ideas of functional programming like currying and partial functional application. You will also explore advanced aspects of the Scala type system like covariance and contravariance, and how to employ the type class pattern when abstracting over concrete types. You will learn about the design of Scala's collections API and how to work with Scala collections effectively. You will get a good grasp of property-based testing, an alternative to example-based testing, and you will dive deeper into sbt, the standard build tool in the Scala ecosystem. You will also learn how to interact with the outside world in a purely functional way, and about different approaches at concurrent programming in Scala.
