Programming Scala Scalability = Functional Programming + Objects 21093

Learn how to be more productive with Scala, a new multi-paradigm language for the Java Virtual Machine (JVM) that integrates features of both object-oriented and functional programming. With this book, you'll discover why Scala is ideal for highly scalable, component-based applications that support concurrency and distribution. Programming Scala clearly explains the advantages of Scala as a JVM language. You'll learn how to leverage the wealth of Java class libraries to meet the needs of practical enterprise and Internet projects more easily. Packed code with examples, this book provides useful information on Scala's command-line tools, third-party tools, libraries, and available language-aware plugins for editors and IDEs. Learn how Scala's succinct and flexible code helps you program faster Discover the notable improvements Scala offers over Java'object model s Get a concise overview of functional programming, and learn how Scala's support for it offers a better approach to concurrency Know how to use mixin composition with traits, pattern matching, concurrency with Actors, and other features essential Take advantage of Scala's built-in support for XML Learn how to develop domain-specific languages Understand the basics for designing test-driven Scala applications Купити книгу Programming Scala Scalability = Functional Programming + Objects
