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


This chapter was more exciting. We learnt about inheritance in Scala and discussed composition and inheritance. It's really going to help us when we take design decisions about our implementation. Then we learnt about this amazing construct named traits and we tried various ways of using traits. Then we learnt about the concept of linearization which it helped us understand how super calls are resolved. Then we talked about packaging and importing which was exciting as Scala provides different ways to use them. Finally, we learnt about visibility rules and sealed traits. And after going through all these concepts, we can say with confidence that we now understand the object-oriented concepts in Scala. So, it's time for us to do some real functional programming. In the next few chapters our focus will be on using functions in Scala.
