官方网站上对Node.js的介绍是 “Node.js is a platform built on  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.”

 

Node 公开宣称的目标是 “旨在提供一种简单的构建可伸缩网络程序的方法”。
