Node.js v7.8.0 发布

摘要:Node.js是一个后端的Javascript运行环境(支持的系统包括Linux、Windows和Mac等)。

 

看到Node.js这个名字,初学者可能会误以为这是一个Javascript应用,事实上,Node.js采用C++语言编写而成,是一个Javascript的运行环境。为什么采用C++语言呢?据Node.js创始人Ryan Dahl回忆,他最初希望采用Ruby来写Node.js,但是后来发现Ruby虚拟机的性能不能满足他的要求,后来他尝试采用V8引擎,所以选择了C++语言。既然不是Javascript应用,为何叫.js呢?因为Node.js是一个Javascript的运行环境。Node.js是一个后端的Javascript运行环境(支持的系统包括Linux、Windows和Mac等),这意味着你可以编写系统级或者服务器端的Javascript代码,交给Node.js来解释执行,Node.js采用了Google Chrome浏览器的V8引擎,性能很好,同时还提供了很多系统级的API,如文件操作、网络编程等。浏览器端的Javascript代码在运行时会受到各种安全性的限制,对客户系统的操作有限。相比之下,Node.js则是一个全面的后台运行时,为Javascript提供了其他语言能够实现的许多功能。
