Tiny javascript implementation?
提问by Dhaivat Pandya
I need an extremely tiny implementation of (maybe a subset of?) Javascript. Code size and memory usage are extremely important (speed isn't in the question, it can run as slow as it likes). It must be written in C (not C++), and that too, ANSI C (GCC extensions are okay). If it runs on a VM would be best, because I will have to write a compiler for it. Any suggestions?
我需要一个非常小的实现（也许是一个子集？）Javascript。代码大小和内存使用非常重要（速度不是问题，它可以随心所欲地运行）。它必须用 C（不是 C++）编写，也必须用 ANSI C（GCC 扩展可以）。如果它在 VM 上运行会是最好的，因为我将不得不为它编写一个编译器。有什么建议？
EDIT: Both of the responses I have seem good, except:
编辑：我的两个回答似乎都很好，除了：
SpiderMonkey concentrates a lot on making it faster, I don't care if its fast at all.
Quad-Wheel sounds good, except the activity on it, and code comments are few (I will be porting this to another architecture if that helps).
SpiderMonkey 非常专注于让它更快，我根本不在乎它是否快。
Quad-Wheel 听起来不错，除了它的活动，而且代码注释很少（如果有帮助，我将把它移植到另一个架构）。
So, any other responses would be great. Or, I could roll out my own simplified version of JS (but that doesn't sound fun at all)
因此，任何其他响应都会很棒。或者，我可以推出我自己的 JS 简化版本（但这听起来一点也不有趣）

I've been looking quite some time for this, since spidermonkey/v8 usually is pretty big and comes with several dependancies. Tiny-js is a portable 'run make and your done'-linux c-class. Perfectly for if you are only looking for simple bindings and prefer javascript/c-syntax over lua/other awesome scriptinglanguages.
我已经为此寻找了一段时间，因为 spidermonkey/v8 通常非常大并且带有几个依赖项。Tiny-js 是一个可移植的'run make and your done'-linux c-class。非常适合如果您只是在寻找简单的绑定并且更喜欢 javascript/c-syntax 而不是 lua/其他很棒的脚本语言。

Mozilla SpiderMonkeyis written in C as well, but probably to complex and large for you?
Mozilla SpiderMonkey也是用 C 编写的，但可能对您来说复杂而庞大？

You should look at Jsi, which was just released. It is very small, is a subset of javascript, and is in C (derived from quadwheel).
你应该看看刚刚发布的Jsi。它非常小，是 javascript 的一个子集，并且是用 C 语言编写的（源自 quadwheel）。

I think the jsi he's talking about is this: http://pdqi.com/cgi-bin/cgiwrap/pdqi/jsi.cgi/doc/tip/jsi/www/usingjsi.wiki
