Introduction to NodeJS
Node.js is an open source server environment that runs on various platforms such as; Windows, Linux, Unix, Mac OS X, etc., it uses JavaScript on the server (A server is a computer program or device that provides a service to another computer program and its user, also known as the client).
Node.js uses asynchronous programming which eliminates the waiting stage of a request and simply continuous with the next request (i.e. you can make a new request while waiting for the result of a previous request.
it can generate dynamic page content, collect form data, perform Sudo (SuperUser DO) actions on server/database (Read, write, delete, modify, add, open create etc.) files, which must have the .js extension.
Getting started with Node.js requires you to download it on your your computer by visiting their official website https://nodejs.org/ where all installation instructions has been made available.
Node.js runs single-threaded, non-blocking, asynchronous programming, which is very memory efficient.
