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());
上面打印的结果：
[Function: Person][Function: Person]undefinedfunctionfunction (name) { ??this.name = name; ??this.gender = [‘man‘, ‘woman‘];}
可以采用toString()的方式对函数进行打印。
node.js打印function
