how to use require in javascript code example

Example 1: Node require module

// Use require.main.require to get a module from the root folder.
const Globals = require.main.require("./globals.js");
const YourCustomModule = require("./yourmodule.js");

console.log(YourCustomModule.message);

// --- yourmodule.js ---
module.exports = {
	message: "Hello World!",
	otherData: "Hello Grepper!"
};

Example 2: javascript require

// The require() method is used to load and cache JavaScript modules.
// So, if you want to load a local, relative JavaScript module into a Node.js application,
// you can simply use the require() method.

// Example:
var yourModule = require( "your_module_name" ); //.js file extension is optional

Example 3: nodejs require

//What is require in Nodejs?
//Node.js follows the CommonJS module system, and the builtin require 
//function is the easiest way to include modules that exist in separate 
//files. The basic functionality of require is that it reads a JavaScript 
//file, executes the file, and then proceeds to return the exports object.
