有JavaScript的本地机器代码编译器吗？ [英] Is there a native machine code compiler for JavaScript?

问题描述

有JavaScript的本地机器代码编译器吗？
我不在说VM。
如果它不存在可以做到吗？

我想知道是否可以编译成二进制由于语言的动态性质。

Is there a native machine code compiler for JavaScript? I'm not talking about a VM. If it doesn't exist can it be done?
I am wondering if it can be compiled to binary due to the dynamic nature of the language.

推荐答案

据我所知，没有JavaScript的静态编译器。这在理论上是可能的;然而，JavaScript的静态编译将需要一个非常重的运行时来支持其所有的功能（如动态类型和eval）。作为一个小问题，当需要静态编译Python（另一种动态语言）时， PyPy 开发人员最终创建了一个语言，这是一个非常有限的Python子集（称为RPython），没有一些Python的更动态的特性，能够静态编译。

As far as I know, there are no static compilers for JavaScript. It is certainly theoretically possible; however, a static compilation of JavaScript would need a very heavyweight runtime to support all of its features (such as dynamic typing and eval). As a small aside, when presented with the need to statically compile Python (another dynamic language), the PyPy developers ended up creating a language which was a very restricted subset of Python (called RPython), void of some of Python's more dynamic features, that was capable of being statically compiled.

如果你要求这是为了从JavaScript代码创建一个独立的可执行文件，我确信必须有包装器，本质上将创建一个可执行文件包含你的脚本和嵌入式JavaScript VM（可悲的是，我不知道有什么不好意思）。

If you're asking this for the purpose of creating a standalone executable from JavaScript code, I'm sure there must be wrappers which essentially would create an executable containing your script and an embedded JavaScript VM (sadly, I don't know any offhand).
