I haven't done any formal benchmarks. A quick test with 1000 sprites runs with 60fps on the iPhone4s. Also try loading this in Mobile Safari and compare it to the video:…

Impressive Canvas-on-OpenGL approach
From 1 comment
That the canvas API is implemented with OpenGL is very impressive. CocoonJS [1] (a similar project for Android, as noted in the comments below) seems to have taken the same…

Maker is a hacker and does great work
From 2 comments
This guy is a hacker in the truest sense, I read a blog post over a year ago about him tinkering away on this. It didn't seem he'd take it this far. It's a great achievement and…
firlefans on HNI used Impact two years ago on something and I was so impressed with the API simplicity and power (not to mention the fact that it ran very well). This guy does great work.

Objections
JIT unavailable on iOS, which may slow JavaScript
From 3 comments
Isn't JS performance going to suffer if it's using a custom build of JSC that can't JIT?
kevingadd on HNNative iOS doesn't have JIT
killahpriest on HNJSC 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…

Only works on iOS, no Android support
From 2 comments
Pretty cool. What about the support for Android, any plans for that?
dsirijus on HNThis 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…

dsirijus on HNThis looks like a great way to build iOS games in HTML5. If he could to get this to work as an Android project it could be used to build games for OUYA.

Usable without Xcode or a Mac
From 1 comment
Any plans on making it usable without XCode? (or a Mac, for that matter.) Since the users just write javascript code, as long as you give them a way to insert that code into an…

Browser version
From 1 comment
I want this in the browser. Throw away the DOM, and let's just have canvas and JS. Skip loading any HTML or CSS. It would be great.

jaipilot747 on HNwebgl can be much faster because you can draw many primitives with one call. there's a lot of overhead from js down to gl.

jaipilot747 on HNReminds me of CocoonJS (basically the same idea, also support for Android but closed source). https://vimeo.com/45506217 Neat in any case. Looks like a nice implementation.

DirectCanvas

DirectCanvas from appMobi (I work there) is based on iOS impact (and enhanced) - http://www.appmobi.com . No need for a Mac or XCode.

Corona

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…
