This is the continuation of the previous part of this tutorial [link] were we when over installation, basic settings, and package versioning.
On the previous part [link], we showed the installation of the package Express. Express is a fast, minimalist web framework built for NodeJS.
var express = require('express');
The method required give us a reference that points to the dependency package Express. However, this doesn’t provide us anything that we can use until we create an instance of Express.
