Learning Scala Programming

By: Vikash Sharma

Overview of this book

Scala is a general-purpose programming language that supports both functional and object-oriented programming paradigms. Due to its concise design and versatility, Scala's applications have been extended to a wide variety of fields such as data science and cluster computing. You will learn to write highly scalable, concurrent, and testable programs to meet everyday software requirements. We will begin by understanding the language basics, syntax, core data types, literals, variables, and more. From here you will be introduced to data structures with Scala and you will learn to work with higher-order functions. Scala's powerful collections framework will help you get the best out of immutable data structures and utilize them effectively. You will then be introduced to concepts such as pattern matching, case classes, and functional programming features. From here, you will learn to work with Scala's object-oriented features. Going forward, you will learn about asynchronous and reactive programming with Scala, where you will be introduced to the Akka framework. Finally, you will learn the interoperability of Scala and Java. After reading this book, you'll be well versed with this language and its features, and you will be able to write scalable, concurrent, and reactive programs in Scala.

Chapter 1. Getting Started with Scala Programming

"When you don't create things, you become defined by your own tastes rather than ability, your tastes only narrow and exclude people. So create."

- Why the Lucky Stiff

Scala is easy to get into but too deep to get a grip on. As the name suggests, Scala means A Scalable Language, a programming language that grows with your programming abilities. This chapter introduces you to this very popular language. 

In this chapter, we will cover the following topics:

  • Introduction to Scala
  • Scala advantages
  • Working with Scala
  • Running our first program
