how to use the this keyword in a module.exports file code example

Example 1: node js module export class

module.exports = class Person {
	constructor(firstName, lastName) {
		this.firstName = firstName;
		this.lastName = lastName;
	}

	display() {
		console.log(this.firstName + " " + this.lastName);
	}
}

Example 2: What is the syntax to export a function from a module in Node.js

function foo() {}
function bar() {}

// To export above functions:
module.exports = foo;
module.exports = bar;

// And in the file you want to use these functions,
// import them like this:
const foo = require('./module/path');
const bar = require('./module/path');
