9. Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non- blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
11. Server-side Javascript Asynchronous Runs on v8 from Chrome Perfect for network programs
