Scala

This international bestseller has been revised with new exercises, annotations, and full coverage of Scala 3.

In Functional Programming in Scala, Second Edition you will learn how to:

• Recognize and write purely functional code
• Work with errors without using exceptions
• Work with state and concurrency
• Interact with functional structures that define common behaviors
• Write code that performs I/O without sacrificing functional programming

Functional Programming in Scala has helped over 30,000 developers discover the power of functional programming. You’ll soon see why reviewers have called it “mindblowing”! The book smooths the complexity curve of functional programming, making it simple to understand the basics and intuitive to progress to more advanced topics. Concrete examples and exercises show you FP in the real world and reveal how it can improve your everyday coding practices. This second edition comes packed with the latest standards of FP, as well as full code updates to Scala 3, and its new language features.

The perfect starting point for your journey into Scala and functional programming.

In Get Programming in Scala you will learn:

• Object-oriented principles in Scala
• Express program designs in functions
• Use types to enforce program requirements
• Use abstractions to avoid code duplication
• Write meaningful tests and recognize code smells

Scala is a multi-style programming language for the JVM that supports both object-oriented and functional programming. Master Scala, and you'll be well-equipped to match your programming approach to the type of problem you're dealing with. Packed with examples and exercises, Get Programming with Scala is the perfect starting point for developers with some OO knowledge who want to learn Scala and pick up a few FP skills along the way.

Get up to speed on Scala--the JVM, JavaScript, 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 building today's highly scalable, data-centric applications, while maximizing developer productivity.

While Java remains popular and Kotlin has become popular, 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.

• Program faster with Scala's succinct and flexible syntax
• Dive into basic and advanced functional programming techniques
• Build killer big data and distributed apps using Scala's functional combinators and tools like Spark and Akka
• Create concise solutions to challenging design problems with the sophisticated type system, mixin composition with traits, pattern matching, and more

Scala 3 is concise, consistent, flexible, robust, and efficient, but there's a lot to learn and navigating features and improvements can be challenging. Scala for the Impatient, Third Edition, is a complete yet concise guide that reflects the major enhancements of Scala 3, from improved syntax and revamped type system to powerful contextual abstractions.

This indispensable tutorial offers a faster, easier pathway for learning today's Scala. Horstmann--author of the programming classic, Core Java--covers everything working developers need to know, focusing on hands-on solutions, not academic theory. Given the size and scope of Scala 3, there's plenty to cover but it's presented in small chunks organized for quick access and easy understanding, with plenty of practical insights and focused sample code.

• Get started quickly with Scala 3 interpreter, syntax, tools, and current usage
• Master core language features: functions, arrays, maps, tuples, packages, imports, exception handling, and more
• Design and build better object-oriented code with Scala 3
• Use Scala for real-world programming tasks: working with files, regular expressions, and processes
• Work with higher-order functions and the powerful Scala collections library
• Create concurrent programs with Scala futures
• Understand the Scala type system, including revamped enums, intersection and union types, and enhanced type inference
• Use contextual abstractions to easily extend class hierarchies, enrich existing classes, perform automatic conversions, and elegantly hide tedious details
• Apply advanced "power tools" such as annotations and given values
• Discover how to "program with types," analyzing and generating types at compile time
• Get a taste of what's now possible with Scala macros

If you're a Java, Python, C++, or C# programmer who's new to Scala or functional programming--or even if you've already used earlier versions of Scala--this guide will help you write code that's more robust, more efficient, and more secure.

Scala in Action is a comprehensive tutorial that introduces Scala through clear explanations and numerous hands-on examples. Because Scala is a rich and deep language, it can be daunting to absorb all the new concepts at once. This book takes a "how-to" approach, explaining language concepts as you explore familiar programming challenges that you face in your day-to-day work.

Scala in Depth is a unique new book designed to help you integrate Scala effectively into your development process. By presenting the emerging best practices and designs from the Scala community, it guides you through dozens of powerful techniques example by example.
