Node.js v7.7.4 发布

<p style="text-align: center;"><strong><img alt="" src="https://simg.open-open.com/show/d9d39e249fe45a3a9d7fbe135ba0644e.png" /></strong></p> <p> </p> <p>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。</p> <h2>更新日志</h2> <ul> <li>[<a href="/misc/goto?guid=4959003579582547712"><code>f48763c5b9</code></a>] -
