This project is very much iOS specific. It's written in Objective-C and uses JavaScriptCore (Apple's JS engine). So porting this over to Android would be a lot of work.

But have a look at CocoonJS; it's cross platform (but closed source): http://ludei.com/tech/cocoonjs

I was curious about that too. With android support, it would be a good alternative to Corona (use js instead of Lua).

For iOS, an added benefit of is that JavascriptCore uses Nitro, unlike UIWebView.

JSC as used by an app store app does not use Nitro. As the post stated, JSC is a private framework and the only way to use it in an approved app is to import the source into your project and build a copy of JSC that is bundled with your app. Since the JSC that you use is contained within your executable, iOS doesn't allow the write and execute permissions in memory that would be necessary for JIT.
