Scala编程(第2版影印版)(英文版)

Scala这种JVM语言通过新式对象模型、函数式编 程和高级类型系统带来的优势提升了语言的运行效率 。这本综合性的书籍——万普勒、佩恩编著的 《Scala编程(第2版影印版)(英文版)》包含了大量的 程序代码示例，向你展示如何在开发中利用语言和生 态系统而立刻变得更具有效率，同时解释了对于当今 支持并发和分布式的高度可扩展的、以数据为中心的 应用程序而言，Scala为什么是一个理想选择。 第2版包含了最新的语言特性，加人了关于模式 匹配、推导和高级函数式编程的新章节。同时你也可 以学习到Scala的命令行工具、第三方工具、库、面 向编辑器和集成开发环境的语言感知插件。这本书是 初级和高级Scala开发人员的理想选择。 这本独一无二的数据科学书籍中的示例代码在一 个公共的GitHub库中得到维护。采用Turnkey Linux 虚拟机可以很容易地访问代码，这有利于基于 IPython Notebooks易用集合的交互式学习。

佩恩，Alex Payne是Twitter的平台领导者，在Twitter他负责开发一些服务，这些服务使得程序员在流行的社交消息服务基础上构建应用。此前Alex为政治组织、非盈利性机构和初创企业构建Web应用。 万普勒，Dean Wampler，Ph D，是一位TypeSafe的大数据架构师。他在Typesafe公司利用Scala、函数式编程、spark、Hadoop以及Akka构建以数据为中心的工具和服务。Dean是《Functional Programming for Java Developers》一书的作者以及《Programming Hive》一书的合著者。
