Node.js is a very performant, open-source, cross-platform, JavaScript runtime environment that executes code outside a web browser. Node.js relies on the V8 JavaScript engine, developed by the Chromium Project for Google Chrome.

According to Node.js

Node.js runs in a single process, without creating a new thread for every request, providing a set of asynchronous I/O primitives in its standard library that prevents JavaScript code from blocking.

The .js suffix does not necessarily represent the standard file extension for JavaScript, but rather the name "Node.js" refers to the name of the product.
