来晚了 
辛苦辛苦了。 
附带点英文。ECMASript 262 标准
1. “ECMAScript is object-based: basic language and host facilities are provided by objects” ECMAScript 基于object: 基本的语言构建及主要功能由objects提供。
2. an object is a member of the remaining built-in type Object; and a function is a callable object。后半句：function是可以调用的object.
3.ECMAScript defines a collection of built-in objects that round out the definition of ECMAScript entities. These built-in objects include the global object, the Object object, the Function object, the Array object, the String object, the Boolean object, the Number object, the Math object, the Date object, the RegExp object. .. ECMAScript定义了一系列内建的objects,这些objects则是对ECMAScript entities（不知道中文用啥词表示）的实现。内建的objects包括 global object, Object object, Function object, Array object, String object 等 ....。
