Introduction

Node.js is a popular back-end JavaScript runtime used for creating web servers and scalable network apps. The environment supports server-side scripting - producing dynamic content for web pages before they are served to the user.

NPM is a package manager for JavaScript and the default package manager for Node.js. As such, NPM is installed alongside Node.js as a recommended feature.
