Scala from Scratch
Scala from Scratch
About the Bundle
Are you curious about functional programming, and why Scala is such a great fit for this paradigm? Is your team considering a switch to Scala? This bundle has all you need to start your journey into Scala.
Scala from Scratch: Exploration gives you an overview of what the language has to offer and what it feels like to program in Scala. By the end of the book, you will have written a small but complete command-line application.
Scala from Scratch: Understanding continues where the first book left off and gives you an in-depth understanding of Scala, including many of its advanced concepts and language features.
About the Books
Scala from Scratch: Exploration
Scala from Scratch: Exploration is the first in a series of two books that teach you the Scala programming language. Readers that have some experience with an object-oriented or imperative language, like Java, Ruby, or Python, will get a comprehensive overview of what Scala brings to the table. The goal is to get you excited about Scala and give you a strong foundation for writing your first applications and continuing your journey. By the end of the book, you will have a good idea of what it's like to work with Scala, and you will have written a small, but complete command-line application based on a Functional Core, Imperative Shell architecture.
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.
If you are excited and want to continue your journey, you will be able to do with the upcoming second book in the series, Scala from Scratch: Understanding, which will go even deeper into the topics explored in this book and will discuss advanced language features and patterns.

Scala from Scratch: Understanding
Scala from Scratch: Understanding is the second in a series of two books that teach you the Scala programming language. Readers that have read Scala from Scratch: Exploration or have learned some Scala through other means will get a deeper understanding of the language features and underlying functional programming concepts that have been explored in the first book. You will also learn about important advanced language features that play a crucial role in many real-life Scala projects. While doing so, you'll get to know best practices that have been established over the years. By the end of the book, you will have a grasp of the language, its idioms, and common tools and techniques, allowing you to be a productive member in commercial or open-source Scala projects.
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.
Some of the content in this book is based on The Neophyte's Guide to Scala. However, it has been heavily revised, and amended with a lot of new content. In some ways, you can think of it as a second, extended edition of that book — structured and written so that it builds on what readers have learned in Scala from Scratch: Exploration.
