in the following code

const express = require('express'); const app = express() app.use(express.static('public')); 

express is a function so how it call "express.static('public')" method on it? is it possible in JavaScript to call a function which is inside a function

 


A functions is not only a first class function, but also a first class object and can contain properties.

function foo() {}  foo.bar = function () { console.log('i am bar'); };  foo.bar();
