10. 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.
