Learn Scala Programming

By: Slava Schmidt

Overview of this book

The second version of Scala has undergone multiple changes to support features and library implementations. Scala 2.13, with its main focus on modularizing the standard library and simplifying collections, brings with it a host of updates. Learn Scala Programming addresses both technical and architectural changes to the redesigned standard library and collections, along with covering in-depth type systems and first-level support for functions. You will discover how to leverage implicits as a primary mechanism for building type classes and look at different ways to test Scala code. You will also learn about abstract building blocks used in functional programming, giving you sufficient understanding to pick and use any existing functional programming library out there. In the concluding chapters, you will explore reactive programming by covering the Akka framework and reactive streams. By the end of this book, you will have built microservices and learned to implement them with the Scala and Lagom framework.

An Introduction to Scala 2.13

At the moment of this writing, Scala 2.13 has reached its five-year milestone and approaches the first release candidate. At this point, its feature set is unlikely to change and it is safe to take a look at the new features of the update.

In this chapter, we will talk about the scope of the release, placing the main focus of the conversation on its centerpiece—the new collection library.

The following topics will be discussed in this chapter:

  • Introduction to Scala 2.13
  • New features of Scala 2.13
  • The Scala 2.13 collection library
