演示代码如下，用JShaman对这段代码进行混淆加密：
function demo(){alert("hello www.jshaman.com");}demo(); 一、通用版
1、配置选项：压缩代码 。
保护效果：
function demo(){alert('hellox20www.jshaman.com');}demo();注：压缩代码会把多行代码去回车、换行等，压缩成一行 。后续代码为展示效果，不启用此选项 。
2、配置选项：平展控制流 。
保护效果：
function demo() {var _0x4a3b8e = {'XmPVw': function (_0x1355fc, _0x5c2d37) {return _0x1355fc(_0x5c2d37);}};_0x4a3b8e['XmPVw'](alert, 'hellox20www.jshaman.com');}demo();3、配置选项：平展控制流、字符串阵列化 。
