商品描述
本書由直接參與Scala開發的一線人員編寫,因而對原理的解讀和應用的把握更加值得信賴。本書面向具有一定編程經驗的開發者,目標是讓讀者能夠全面瞭解和掌握Scala編程語言的核心特性,並能夠深入理解Scala這門語言在設計取捨背後的動因。即便是不直接使用Scala或從事一線編程工作的讀者,也能從本書學到大量關於函數式和麵向對象的編程概念和技巧。
作者簡介
作者:(德)Martin Odersky(馬丁.奧德斯基)、(美)Lex Spoon(萊·斯彭),(美)Bill Venners(比爾·凡納斯) 譯者:高宇翔
Martin Odersky 是Scala 編程語言的締造者。他是瑞士洛桑理工學院(EPFL)的教授,同時也是Typesafe, Inc.(已更名為Lightbend)的創始人。他的研究方向是編程語言和系統,更具體地說,就是如何將面向對象和函數式編程風格有機地結合在一起。自2001 年起,他的主要精力集中在設計、實現和改進Scala 上。在此之前,他作為Java 泛型的合作設計者參與了Java 編程語言的開發,同時也是當前javac 參考實現的作者。他還是ACM 院士。Lex Spoon 是Semmle Ltd. 的一名軟件工程師。他在EPFL 作為博士後圍繞著Scala 開展了兩年的工作。他擁有Georgia Tech 的博士學位,在那裡他的主攻方向是動態編程語言的靜態分析。除Scala 外,他還幫助開發了各類編程語言,包括動態語言Smalltalk、科學計算語言X10,以及支撐Semmle 的邏輯編程語言。他和他的夫人一起生活在Atlanta,他們有兩隻貓和一隻吉娃娃。Bill Venners 是Artima Inc. 的主席,Artima 開發者網站(ww.artima.com)的發行人,以及Escalate Software, LLC 的聯合創始人。他著有《Inside theJava Virtual Machine》,這是一本面向程序員講解Java 平台架構和內部實現原理的書。他在《JavaWorld》雜誌上的專欄很受歡迎,主題涵蓋Java 內部實現、面向對象的設計和Jini。Bill 從Jini 社區創立之初便十分活躍,領導了Jini 社區的ServiceUI 項目,其API 成為Jini 服務事實上的UI 標準。他還是ScalaTest 的主要開發者和設計者,一個面向Scala 和Java 開發者的開源測試工具。
高宇翔,資深軟件開發工程師和系統架構師,同時也是Scala在國內的早期佈道者和實踐者,曾譯有《快學Scala(第2版)》、《快學Scala》(第1版)和《 Scala編程》(第1版)等專業書籍。
