How object has anonymous function in Node.js

in Node.js, process.hrtime is Object like that

hrtime: { [Function: hrtime] bigint: [Function] }, (in pcoress object)

hrtime can be executed by process.hrtime() and has key bigint as a function that executed by process.hrtime.bigint().

i wonder how it possible hrtime is a function and object at the same time.

i tried to include anonymous function in object, but failed.

how can i make it?

process {
  title: 'node',
  version: 'v10.16.3',
...
  hrtime: { [Function: hrtime] bigint: [Function] },
...
}

You can assign properties on functions like you can onto any object.

function x() {
  console.log("You have successfully called x()!");
}

function y() {
  console.log("Hello, this is y()!");
}

x.y = y;

x();
x.y();

prints out

You have successfully called x()!
Hello, this is y()!
