Node.js Runtime Environment Overview

Node.js, founded by Ryan Dahl in 2009, is an open-source, cross-platform JavaScript runtime environment designed for running JavaScript code outside of web browsers. It utilizes Google Chrome's V8 JavaScript engine and supports various operating systems including Windows, Linux, Unix, and Mac OS X. Node.js features event-driven and non-blocking I/O models, making it ideal for handling concurrent connections in real-time applications such as online games, chat apps, and messaging services. With its modular architecture and npm (Node package manager), Node.js fosters code sharing and reuse among developers, enhancing its ecosystem and supporting applications beyond server-side development. Major enterprises like Netflix, PayPal, and Walmart leverage Node.js for improved performance, streamlined development processes, and rapid market responsiveness.
