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.

Summary


We can conclude our chapter; let's go through what we have learned. We started learning about looping constructs in Scala. We discussed native looping constructs such as for,while, and do while loops. After that, we saw for expressions, along with for yield expressions. Then we understood alternatives to iteration, that is, recursion. We wrote a few recursive functions as well. Finally, we looked at if else conditional statements and pattern matching. We know there's much more to come, but with these concepts we're on our way to understanding Scala language constructs better. We'll continue doing that in our next chapter. There we'll take a look at the core of functional programming: functions. We will see how functions are defined and used. It'll show the variety of functional constructs we have available in Scala. We'll try to give meaning to our programs using functions.
