请问我如何让b的this,显示为Person{name: "aa", age: "18"},谢谢

请问我如何让b的this,显示为Person{name: "aa", age: "18"},就是绑定到main.js里实例化的对象上,谢谢
//a.js

var a=function(){console.log("我是a")}
export {a}

//b.js

var b=function(){console.log(this)}
export {b}

//main.js

import {a} from './a'
import {b} from './b'

var f=function Person(name, age) {
    this.name = name
    this.age = age
    console.log(this) 
}
var c=new f('aa','18')// Person{name: "aa", age: "18"}
a()
b()
