Node.js v21.6.2 for Linux ARM64

Node.js, or simply Node, is an open-source, cross-platform JavaScript runtime environment that allows JavaScript code to be executed outside of a browser. Created by Ryan Dahl in 2009, Node.js aims to build high-performance web servers and network applications. It is based on Google Chrome's V8 JavaScript engine and can run on operating systems like Windows, Linux, Unix, and Mac OS X. One of Node.js's key features is its event-driven, non-blocking I/O model, making it highly suitable for handling a large number of concurrent connections. This makes it ideal for real-time applications like online games, chat applications, and real-time communication services. Additionally, Node.js employs a modular architecture, and through npm (Node package manager), community members can share and reuse code, significantly boosting the growth and expansion of the Node.js ecosystem. Node.js is not only used for server-side development. With technological advancements, it is also utilized for building toolchains, developing desktop applications, and IoT devices. Node.js can manage file systems, operate databases, and handle network requests, enabling developers to write full-stack applications in JavaScript, greatly enhancing development efficiency and convenience. In practice, many large enterprises and organizations, such as Netflix, PayPal, and Walmart, have adopted Node.js as their web application development platform. They leverage Node.js to improve application performance, streamline development processes, and quickly respond to market demands.
