什么是 scala http://www.scala-lang.org/ scala 是 Scalable Language 的简写，由 Martin Odersky (Generic Java 的作者 ) 发明，目的就是创造一个 jvm 上的高度可扩展的语言。 2003 诞生，前身是 Pizza （ 1996 ，晚 java 一年）、 Funnel ，最新版本是 2.9.0.1 ，它具有以下特性： 1.It has an event-based concurrency model. （基于事件的并行模式） 2.It supports both an imperative style and a functional style. （支持命令式和函数式编程） 3.It is purely object-oriented. （纯粹的面向对象） 4.It intermixes well with Java. （和 java 的完美混合） 5.It enforces sensible static typing. （强制静态） 6.It is concise and expressive. （简洁且易于表达的） 7.It is built on a small kernel. （只有一个很小的核心） 8.It is highly scalable, and it takes less code to create high-performing applications. （易于扩展，只用很少的代码即可写出高性能的程序。 type less ， do more ）
