  <blockquote>
    <p>Node.js is a platform built on Chrome's <strong>JavaScript run-time</strong> 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.</p>
