Node.js Runtime Environment Overview

Node.js, abbreviated as Node, is an open-source, cross-platform JavaScript runtime environment. It enables JavaScript code execution outside the browser. Founded by Ryan Dahl in 2009, Node.js is built on Google Chrome's V8 JavaScript engine, supporting Windows, Linux, Unix, and macOS. Noteworthy for its event-driven, non-blocking I/O model, Node.js excels in handling concurrent connections, ideal for real-time applications like online gaming, chat apps, and communication services. Node.js utilizes a modular architecture and npm (Node package manager) for code sharing and reuse, fostering its ecosystem growth. Beyond servers, Node.js is used in toolchains, desktop apps, and IoT devices, facilitating full-stack JavaScript development for improved efficiency and responsiveness. Major enterprises like Netflix, PayPal, and Walmart leverage Node.js for enhanced application performance and streamlined development processes.
