I've recently begun hearing a great deal about Node.js. While I understand a few things that it's able to do, namely create a web server, I'm wondering if you could provide me with a solid reasoning behind using this functionality in a production environment.
我最近开始听到很多关于Node.js.的内容。虽然我理解了它可以做的一些事情，即创建一个Web服务器，但我想知道你是否可以在生产环境中为我提供一个可靠的推理。
This article made a solid case for using Node.js as a development tool, essentially stating that it can provide the usability of a backend environment without needing backend experience. I've also heard of many developers using Node.js in production projects (Codepen for example), but I simply don't understand how it can be useful when there are established web servers out there such as a LAMP stack.
本文为使用Node.js作为开发工具奠定了坚实的基础，本质上说明它可以提供后端环境的可用性而无需后端体验。我也听说过很多开发人员在生产项目中使用Node.js（例如Codepen），但是当我们在那里建立了Web服务器（如LAMP堆栈）时，我根本不明白它是如何有用的。
I would love to invest the time into learning about Node.js due to its growing popularity, but because I do have a fairly solid backend foundation, I'm curious if it's necessary.
我很想花时间学习Node.js，因为它越来越受欢迎，但因为我确实有一个相当坚实的后端基础，我很好奇是否有必要。
In short, what are some of the most useful aspects of Node.js and why would someone need to use in a production environment?
简而言之，Node.js的一些最有用的方面是什么以及为什么有人需要在生产环境中使用？

Scalability is often the big reason. End to end javascript is also a popular answer. Also Node is good at making some potentially complicated "real-time" scenarios almost trivial when using a library like socket.io.
可伸缩性通常是最重要的原因。端到端javascript也是一个流行的答案。在使用像socket.io这样的库时，Node也很擅长使一些可能复杂的“实时”场景变得微不足道。
