Scala這種JVM語言通過新式對象模型、函數式編程和高級類型係統帶來的優勢提升瞭語言的運行效率。

《Scala編程（第2版 影印版 英文版）》包含瞭大量的程序代碼示例，嚮你展示如何在開發中利用語言和生態係統而立刻變得*具有效率，同時解釋瞭對於當今支持並發和分布式的高度可擴展的、以數據為中心的應用程序而言，Scala為什麼是一個理想選擇。

第2版包含瞭新的語言特性，加人瞭關於模式匹配、推導和高級函數式編程的新章節。同時你也可以學習到Scala的命令行工具、第三方工具、庫、麵嚮編輯器和集成開發環境的語言感知插件。

《Scala編程（第2版 影印版 英文版）》是初級和高級Scala開發人員的理想選擇。

《Scala編程（第2版 影印版 英文版）》數據科學書籍中的示例代碼在一個公共的GitHub庫中得到維護。采用Turnkey Linux虛擬機可以很容易地訪問代碼，這有利於基於IPython Notebooks易用集閤的交互式學習。
