Download Node.js 8.0.0

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, we refer you to this page. The development team has released version 8.0.0 with the following changes:
