It is very unclear what you're trying to achieve here.

You're exporting a function. That function will take 1 argument (d). Then you try to assign the demo1 and demo2 properties, of that received argument, to two different functions.

What I think you want to do is that you want to export an object with two different properties for those functions. E.g. doing this:

module.exports = {
  demo1: function() {
    return "DEMO 1";
  },

  demo2: function() {
    return "DEMO 2";
  }
}

Then you can import the module and access the demo1 and demo2 functions as:

var demo = require('./test1');
var result = demo.demo1();

I know this, but i am trying this in different way which i ask you. Thanx i got solution from #user1280859 — Raju Kumar, Apr 01 '16 at 09:08

var demo = require('./test1');
var o = {};
demo(o);
o.demo1(); // "DEMO 1";
