The Scala Programming Language

Scala combines object-oriented and functional programming in one concise, high-level language. Scala's static types help avoid bugs in complex applications, and its JVM and Javascript runtimes let you build high-performance systems with easy access to huge ecosystems of libraries.

Scala将面向对象得编程和函数式编程结合在一个简洁得高级语言中。Scala得静态类型有助于避免复杂应用程序中得错误，其JVM和Javascript运行时使您可以轻松访问庞大得库生态系统来构建高性能系统。
