ES6 module: re-export as object

Question

I have moduleA which exports some functions:

// moduleA.js
export function f1() {...}
export function f2() {...}

Is there any way to re-exp

Answer 1

file1.js

export let uselessObject = {
  con1 : function () {
    console.log('from file1.js')
  }
}

file2.js

import { uselessObject } from './file1.js'

uselessObject.con2 = function(){
  console.log('from file2.js ')
}

export { uselessObject } from './file1.js'

Index.js

import { uselessObject } from './file2.js'
uselessObject.con1()
uselessObject.con2()

Output

from file1.js
from file2.js
