node@22 for Mac

Node.js is an open-source, cross-platform JavaScript runtime environment that enables developers to write server-side programs, web applications, command-line tools, and various scripts in JavaScript. It frees JavaScript from the browser, allowing the same language to handle both frontend and backend logic, reducing the cost of switching between languages. For frontend developers, it is the foundation for setting up local development environments, running build tools, and executing package management commands; for backend developers, it provides an event-driven, non-blocking model suited to handling large numbers of concurrent connections. node@22 refers to the 22nd major version of this runtime environment, which can be invoked via the command line. Whether you are a newcomer just getting started with JavaScript or an experienced developer who needs to quickly build server-side prototypes, it can serve as one of the basic tools for daily development.
