    • What's Scala? ● Scala ● Is a general purpose programming language. ● stands for "scalable language” – is designed to grow with the demands of its users.
    • What's Scala? ● Scala ● Runs on Java VM. – You can call Scala from Java – and you can call Java from Scala. ● whose compiler produces – byte code that performs every bit as good as comparable Java code.
    • What's Scala? ● James Gosling: ● "Which Programming Language would you use *now* on top of JVM, except Java?" ● James Gosling:”Scala.” ● http://www.adam- bien.com/roller/abien/entry/java_net_javaone_ which_programming
    • What's Scala? ● James Strachan: ● “I can honestly say if someone had shown me the Programming in Scala book by by Martin Odersky, Lex Spoon & Bill Venners back in 2003 I'd probably have never created Groovy.” ● http://macstrac.blogspot.com/2009/04/scala- as-long-term-replacement-for.html
    • What's Scala? ● Charles Nutter: – “Scala, it must be stated, is the current heir apparent to the Java throne. No other language on the JVM seems as capable of being a "replacement for Java" as Scala.” – http://blog.headius.com/2009/04/future- part-one.html
    • What's Scala? ● Scala ● Is a pure object-oriented language. – Type inference – Static typing – Every value is an object. val a = 12345 a.toString
    • What's Scala? ● Scala ● Is a pure object-oriented language. – Classes and traits. – Extend by subclassing and mixin- based composition.
    • What's Scala? ● Scala ● Is functional. – Every function is a value. val func = (x : Int) => x + 1 func(1)
    • What's Scala? ● Scala ● Is functional. – Higher-order functions – Nesting functions – Currying
    • What's Scala? ● Scala ● Is functional. – Case classes and built-in support for pattern matching – Built-in support for XML processing!
    • What's Scala? ● XML Sample val html = <html><head>foo</head> <body>hoge</body></html> println(html)
