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.
@mashiro 搞不懂后端用JS能增加啥BUFF，求解 
@233mc44 其实当今最大的优势的还是有完善的生态链，性能更好的语言是有，比如crystal，但是没有生态，轮子都得从头造啊
@233mc44 那个呀，你代码多一点可就维护不过来了
