Software Update: Node.js 12.0.0

Node.js is open source and platform independent, and is focused on developing server-side web applications. Those applications are written in JavaScript and run within the Node.js runtime on the server. It offers an event-driven environment where non-blocking I/O has been an important starting point. For more information, please refer to this page. The development team has released version 12.0.0 in the current branch. The list of changes looks like this:
