这是一个支持动态类型的脚本语言，支持函数式编程和prototype based面向对象的OO开发。这个语言同Java可以无缝衔接：可以容易的访问Java的类，同时可以被Java的代码调用。
同Python、Ruby和Groovy相比，这个语言的语法相对更接近Java。所以熟悉Java的朋友学习起来很容易。
这个动态类型的脚本语言可以极大地加快你的开发速度，让你可以轻松完成开发任务。

下面是一个用Swing类库的计算器程序的示范程序。
运行方法:
(1) 你必须有JRE 1.6或者1.7已经安装
(2) 下载OrangeScript.jar
wget http://www.stonezhong.net/orangescript/OrangeScript.jar
(3) 下载计算器源码
wget http://www.stonezhong.net/orangescript/contents/examples/calculator.os
(4) 运行
java -classpath OrangeScript.jar orangeScript.parser.Main -file calculator.os
