直接new Person()不就行了，何必多此一举 `var _Person = function() {}; _Person.prototype = Person.prototype; var me = new _Person(); `
@ginnko 2去掉之后remaining就一直等于wait，if 语句还怎么执行
**发现另外一个bug：** 假如obj的constructor重写，并且constructor.ptototype重写toString `var Func = function() {}; Func.prototype.toString = null; var obj = { constructor: Func };` // 返回值是 =>是["constructor", "toString"] 问题出在这句 `obj[prop] !== proto[prop] `
@sqfbeijing 为什么不行，可以的啊，严格模式只是淘汰了arguments.callee 和 arguments.caller
方法三： ` return !pos || item != ary[pos - 1];` 换成 ` return !pos || item !== ary[pos - 1];` 使用严格相等应该就行了吧
