网络开发者是否仍然要学习JavaScript？ [英] Should web developers still learn JavaScript?

问题描述

现在像GWT，Morfik等框架已经将Java客户端代码编译成主要的JavaScript方言，它仍然值得学习JavaScript吗？

解决方案在我的书中，是。

我深信无论您使用哪种工具包，都能理解底层技术使用。

抽象是有漏洞的 - 如果您只想了解高级工具包，而不是底层技术，您会遇到麻烦。迟早你需要在JavaScript（或其他）级别上调试你的项目。

Now that frameworks like GWT, Morfik etc exist which compile Java client side code into major JavaScript dialects, is it still worth learning JavaScript?

解决方案

In my book, yes.

I'm a strong believer in understanding the underlying technology beneath whatever toolkits you're using.

Abstractions are leaky - you'll run into trouble down the line if you try to get away with only understanding a high-level toolkit, and not the underlying technology. Sooner or later you'll need to debug your project at the JavaScript (or whatever) level.
