Windows 8可以编译JavaScript吗? [英] Does Windows 8 Compile JavaScript?

问题描述

令人振奋的是，Windows 8为Metro App开发支持了许多语言.使我特别感兴趣的一个是HTML5/CSS/JavaScript.我不明白的是，此代码是否将以某种可执行文件(例如C#，VB和C ++选项)进行编译，或者我的应用程序基本上会在IE中作为实际的网页运行?

It is exciting that Windows 8 is supporting so many languages for Metro App development. One that especially interested me was the HTML5/CSS/JavaScript. What I don't understand, is this code going to get compiled in a sort of executable (like the C#, VB, and C++ option), or would my app basically be running in IE as an actual web page?

推荐答案

是. Chakra引擎在Windows 8上执行Javascript.与.NET即时编译器类似，它可以将javascript转换为优化的机器代码.也是Google的V8和Mozilla的TraceMonkey引擎采用的方法.一些背景信息

Yes. Javascript is executed on Windows 8 by the Chakra engine. Similar to the .NET just-in-time compiler, it translates javascript to optimized machine code. Also the approach taken by Google's V8 and Mozilla's TraceMonkey engines. Some background info is here.
