You can use exports which is an empty object as:
var app = exports;
app.yaha = 'jjj';
app.yahajk = 'eklj';
app.echo = function(){
console.log(this.yaha);
};
or you can use assign your thing to module.exports:
var app = {};
app.yaha = 'jjj';
app.yahajk = 'eklj';
app.echo = function(){
That's how javascript works. If you assign an object `a` to `b`, you're
assigning the reference. You are not making a copy. If you modify one, the
change will reflect on both since they both point to the same object.

correct, but harder to understand explanation.

`exports` is simply a variable containing a reference to `module.exports`.
`module.exports` is an empty object to start, so you can start assigning
stuff to its properties right away.
So when you have `var app = exports`, you're using `app` as a reference to
the object assigned to
thanks you
