Function与Object

 

   先看一段代码：

 

Function instanceof Object;  //true
Object instanceof Function;  //true

 

    Function和Object互为各自的实例

 

function Foo(){};

var foo = new Foo();


foo instanceof Foo;  //true
foo instanceof Object;  //true
foo instanceof Function; //false

Foo instanceof Function; //true
Foo instanceof Object;  //true
