Node.js v17.0.1 for Mac OS X (64-bit)

Node.js, abbreviated as Node, is an open-source, cross-platform JavaScript runtime environment that allows JavaScript code to run outside of a browser. Created by Ryan Dahl in 2009, it aims to build high-performance web servers and network applications. Based on Google's V8 JavaScript engine, Node.js can run on Windows, Linux, Unix, and Mac OS X. Its event-driven and non-blocking I/O model makes it ideal for handling many concurrent connections, excelling in building real-time applications such as online games, chat applications, and real-time communication services. Additionally, Node.js uses a modular architecture through npm (Node package manager), enabling community members to share and reuse code, significantly promoting the development and expansion of the Node.js ecosystem. Beyond server-side development, Node.js is also used for building toolchains, desktop applications, and IoT devices. It can handle file systems, operate databases, and process network requests, allowing developers to write full-stack applications in JavaScript, greatly enhancing development efficiency and convenience. Many large enterprises and organizations, such as Netflix, PayPal, and Walmart, have adopted Node.js as their web application development platform, leveraging it to improve application performance, simplify development processes, and respond more quickly to market demands.
