reference function in object in another key function

Question

I have an module exported as the following, I want to call function in another is that possible in that case

module.exports = {
  first:() => {
    // this is my first function
  },
  second:() => {
    // I want to call my first function here
    // I have tried this 
    this.first()

  }
}

you can define the functions before exporting and reuse them however you want. — Ramesh Reddy, Jan 17 '21 at 11:38
Ok I know this way but I thought there is might be another way to do it as it is — mohamed nageh, Jan 17 '21 at 11:41
Wouldn’t just using a normal function instead of an arrow function fix the issue? — Strahinja Ajvaz, Jan 17 '21 at 11:49
I have used the function keyword but it didn't solve it @strahinja — mohamed nageh, Jan 17 '21 at 12:07

You can define module.exports at first in a variable and use it in second as follows:

First file (other.js):

const _this = (module.exports = {
  first: () => {
    console.log("first");
  },
  second: () => {
    _this.first();
  }
});

Second file (index.js):

import other from "./other";

other.second();

Output:

first

You can access it from the other module like this

const {first, second } = require('./module2');
first();
second();

or

const collectedFunctions = require('./module2');

collectedFunctions.first();
collectedFunctions.second();
