在网页编程中，除了搞前端要用到JS之外，你还会在别的地方大范围使用JS么？

@233mc44 现在不是都在说大前端么，就算Mastodon这样Rails后端的项目，后端仍有一大块是js做的，js runtime了解一下：

Node.js is a platform built on Chrome’s JavaScript run-time 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.
