Book Description
Write efficient, clean, and powerful Scala code and create high-performing applications that your users will loveAbout This Book*This is the first book that explores Scala performance techniques in depth, including how to benchmark your performance so you can understand where to make gains*It provides a first-principles examination of what performance means in a Scala context*This book was written by industry experts Vincent Theron and Michael DiamantWho This Book Is ForIf you are a Scala developer with experience in programming Scala applications and know the basics in Scala, syntax, and frameworks such as Lift or Play, this book is for you. This book will also be useful if you are a Java developer who is interested in switching to Scala, but you don't want to give up the performance of Java code. No knowledge of anything outside Scala is required.What You Will Learn*Find out about performance and how to evaluate the behavior of an application*Analyze the performance of your application on JVM*Use Scala features to achieve a high performance benchmark for your application*Enhance the performance of your application with the Collection API*Explore asynchronous programming to achieve concurrency and parallelism*Achieve a deeper understanding of high performance using advanced toolsIn DetailScala is a statically and strongly typed language that tries to elegantly blend both functional and object-oriented paradigms. It has experienced growing popularity in the past few years as both an appealing and pragmatic choice to write production-ready software in the functional paradigm. Scala lets you solve problems with less code than the alternatives. However, this programmatic gain can come at the cost of performance if you aren't careful.Scala High Performance Programming is written to arm you with the knowledge you need to create highly efficient, clean Scala applications. Starting with the basics of understanding what performance is in a Scala context, we'll look at how to benchmark your performance so you can see the results of your optimizations in action. We'?ll also take a deep dive into type specialization, concurrency, and parallel programming. By the end of the book, you'll be able to code efficient, optimized, solutions in Scala.

Book Description
Access the power of bare-metal systems programming with Scala Native, an ahead-of-time Scala compiler. Without the baggage of legacy frameworks and virtual machines, Scala Native lets you re-imagine how your programs interact with your operating system. Compile Scala code down to native machine instructions; seamlessly invoke operating system APIs for low-level networking and IO; control pointers, arrays, and other memory management techniques for extreme performance; and enjoy instant start-up times. Skip the JVM and improve your code performance by getting close to the metal. Developers generally build systems on top of the work of those who came before, accumulating layer upon layer of abstraction. Scala Native provides a rare opportunity to remove layers. Without the JVM, Scala Native uses POSIX and ANSI C APIs to build concise, expressive programs that run unusually close to bare metal. Scala Native compiles Scala code down to native machine instructions instead of JVM bytecode. It starts up fast, without the sluggish warm-up phase that's common for just-in-time compilers. Scala Native programs can seamlessly invoke operating system APIs for low-level networking and IO. And Scala Native lets you control pointers, arrays, and other memory layout types for extreme performance. Write practical, bare-metal code with Scala Native, step by step. Understand the foundations of systems programming, including pointers, arrays, strings, and memory management. Use the UNIX socket API to write network client and server programs without the sort of frameworks higher-level languages rely on. Put all the pieces together to design and implement a modern, asynchronous microservice-style HTTP framework from scratch. Take advantage of Scala Native's clean, modern syntax to write lean, high-performance code without the JVM. What You Need: A modern Windows, Mac OS, or Linux system capable of running Docker. All code examples in the book are designed to run on a portable Docker-based build environment that runs anywhere. If you don't have Docker yet, see the Appendix for instructions on how to get it.

Book Description
Why learn Scala? You don’t need to be a data scientist or distributed computing expert to appreciate this object-oriented functional programming language. This practical book provides a comprehensive yet approachable introduction to the language, complete with syntax diagrams, examples, and exercises. You’ll start with Scala's core types and syntax before diving into higher-order functions and immutable data structures. Author Jason Swartz demonstrates why Scala’s concise and expressive syntax make it an ideal language for Ruby or Python developers who want to improve their craft, while its type safety and performance ensures that it’s stable and fast enough for any application. Learn about the core data types, literals, values, and variables Discover how to think and write in expressions, the foundation for Scala's syntax Write higher-order functions that accept or return other functions Become familiar with immutable data structures and easily transform them with type-safe and declarative operations Create custom infix operators to simplify existing operations or even to start your own domain-specific language Build classes that compose one or more traits for full reusability, or create new functionality by mixing them in at instantiation
