node-v0.8.10-sunos-x64.tar.gz

Node.js,简称Node,是一个开源且跨平台的JavaScript运行时环境,它允许在浏览器外运行JavaScript代码。Node.js于2009年由Ryan Dahl创立,旨在创建高性能的Web服务器和网络应用程序。它基于Google Chrome的V8 JavaScript引擎,可以在Windows、Linux、Unix、Mac OS X等操作系统上运行。 Node.js的特点之一是事件驱动和非阻塞I/O模型,这使得它非常适合处理大量并发连接,从而在构建实时应用程序如在线游戏、聊天应用以及实时通讯服务时表现卓越。此外,Node.js使用了模块化的架构,通过npm(Node package manager,Node包管理器),社区成员可以共享和复用代码,极大地促进了Node.js生态系统的发展和扩张。 Node.js不仅用于服务器端开发。随着技术的发展,它也被用于构建工具链、开发桌面应用程序、物联网设备等。Node.js能够处理文件系统、操作数据库、处理网络请求等,因此,开发者可以用JavaScript编写全栈应用程序,这一点大大提高了开发效率和便捷性。 在实践中,许多大型企业和组织已经采用Node.js作为其Web应用程序的开发平台,如Netflix、PayPal和Walmart等。它们利用Node.js提高了应用性能,简化了开发流程,并且能更快地响应市场需求。
