What is nodejs?

First of all, it is very important to understand that Node is not a web server. It doesn't do anything by itself. It doesn't work like Apache. If you want it to be an HTTP server, you have to write it yourself with the help of its built-in libraries. Node.js is just another way to execute code on the computer. It is a simple JavaScript Runtime.

Simply put, Node.js is JavaScript running on the server.

Node.js is a platform built on the Chrome JavaScript runtime.

Node.js is an event-driven I/O server-side JavaScript environment based on Google's V8 engine. The V8 engine executes Javascript very quickly and has very good performance.
