Node.js v18.2: An Overview

Node.js, an open-source, cross-platform JavaScript runtime, enables the execution of JavaScript code outside of browsers. Established by Ryan Dahl in 2009, Node.js aims to build high-performance web servers and network applications. Utilizing the Google Chrome V8 JavaScript engine, it operates across various operating systems, including Windows, Linux, Unix, and macOS. A key feature of Node.js is its event-driven, non-blocking I/O model, ideal for managing numerous concurrent connections, which is beneficial for real-time applications like online games and chat services. Node.js’s modular architecture, supported by npm (Node package manager), fosters code sharing and ecosystem expansion. Beyond server-side development, Node.js is used for building toolchains, desktop applications, and IoT devices. Its ability to handle file systems, databases, and network requests allows developers to create full-stack applications efficiently. Major organizations, such as Netflix, PayPal, and Walmart, utilize Node.js to enhance application performance, streamline development, and adapt quickly to market demands.
