In this article we will be going over the general process of how to install Node.js and NPM on an Ubuntu 18.04 machine.
Node.js which is a popularly known as ???Node??? is an open source cross-platform JavaScript run-time environment which is built on Google Chromes V8 engine that allows server-side execution of JavaScript code.
This simply means that you can run JavaScript code on your machine as a standalone application, free of any web browser which has traditionally been the only place that JavaScript code can run.
Node.js does not have a rendering engine for CSS nor does it do have a DOM parser but does have things you need in a server like an HTTP library and a filesystem API. It is mainly used to build back-end server-side applications, but it is also very popular as a full-stack and front-end solution.
