Wampler D. Programming Scala. Scalability...3ed 2021

Textbook in PDF format

Get up to speed on Scala—the JVM, jаvascript, and natively compiled language that offers all the benefits of functional programming, a modern object model, and an advanced type system. Packed with code examples, this comprehensive book shows you how to be productive with the language and ecosystem right away. You’ll learn why Scala is ideal for today’s highly scalable, data-centric applications that support concurrency and distribution.
Despite the reinvigoration of Java and the introduction of Kotlin, Scala hasn’t been sitting still. This third edition covers the new features in Scala 3.0, with updates throughout the book. Programming Scala is ideal for beginning to advanced developers who want a complete understanding of Scala’s design philosophy and features with a thoroughly practical focus.
Forward-looking programming languages don’t always make it. Yet Scala is not only surviving but thriving. Some languages never get commercial adoption at all. Those first few companies brave enough to bet their business on your language are hard to find. Other languages get their time in the commercial sun but don’t manage to hang on, like Common Lisp and Smalltalk. They live on as influences, their genes still discernable in contemporary languages. That’s success of a kind, but not what the creators wanted.
Programming Scala introduces an exciting and powerful language that offers all the benefits of a modern object model, functional programming (FP), and an advanced type system, while leveraging the industry’s investment in the Java Virtual Machine (JVM). Packed with code examples, this comprehensive book teaches you how to be productive with Scala quickly, and explains what makes this language ideal for today’s scalable, distributed, component-based applications that support concurrency and distribution. You’ll also learn how Scala takes advantage of the advanced JVM as a platform for programming languages.
