Node.js Overview

Node.js is a cross-platform JavaScript runtime environment known for its event-driven and non-blocking I/O model, making it suitable for real-time applications such as online gaming, chat apps, and communication services. It utilizes the V8 JavaScript engine from Google Chrome and can run on various operating systems including Windows, Linux, Unix, and Mac OS X. Node.js features modular architecture and leverages npm (Node package manager) for code sharing and reuse, fostering the growth of its ecosystem. Besides server-side development, Node.js is used for building tools, desktop apps, IoT devices, and more, enabling developers to write full-stack applications in JavaScript and enhancing development efficiency and convenience. Many large enterprises like Netflix, PayPal, and Walmart use Node.js to improve application performance, streamline development processes, and respond quickly to market demands.
