Node.js Runtime Environment Overview and Applications

Node.js, founded by Ryan Dahl in 2009, is an open-source, cross-platform JavaScript runtime environment. It utilizes Google Chrome's V8 JavaScript engine and supports various operating systems including Windows, Linux, Unix, and Mac OS X. Node.js is event-driven with a non-blocking I/O model, making it ideal for real-time applications such as online gaming, chat apps, and communication services. It features a modular architecture and leverages npm (Node package manager) for code sharing, enhancing its ecosystem. Besides server-side development, Node.js is employed in tooling, desktop app development, and IoT devices, facilitating full-stack JavaScript development and improving efficiency.
