var Person = function(name) {
this.name = name;
this.gender = [‘man‘, ‘woman‘];
}
console.log(Person);
console.dir(Person);
console.dir(JSON.stringify(Person));
console.log(typeof(Person));
console.log(Person.toString());

上面打印的結果：

[Function: Person]
[Function: Person]
undefined
function
function (name) {
   this.name = name;
   this.gender = [‘man‘, ‘woman‘];
}

可以采用toString()的方式對函數進行打印。
