(edit: this sounds a little negative... what i mean is, pointing to a really slick html5 game on the app store would make selling the book a lot easier)
HTML5 game development on Android is a performance nighmare. Even if it was true that v8 was used in Android Browser or Android WebView (it isnt), it doesnt matter, it is the horrible draw performance that is the bottleneck (both canvas and css translate3d).
There are some CocoonJS games in the store, you can see some here: http://ludei.com/games CocoonJS will give your HTML5 game native performane.
Native performance is wrong, javascript (unless it's like asm.js or something) will never be "native performance".
All CocoonJS is, is just a OpenGL layer with html/css/javascript support. And while it is faster then just flat out using JSC. It is not faster then c/objective c + opengl.
There have also been several reports of CocoonJS actually being slower then UIWebView. A simple google search for "cocoonjs performance" returned several issues.
I am playing right now with Ejecta which translates JavaScript to ObjectiveC, and then I get a very good speed, no matter how I rotate the screen.
For example, take your home page: "You’re interested in making games or other interactive HTML5 apps, but you don’t quite know were to start and what you will need to accomplish that."
That should be "where", not "were".
For example...
The canvas is a native HTML-element that can be used to draw and alternate images and render its output to an HTML document. Drawing-methods can be accessed directly through the context of the canvas, however EaselJS will add a layer of abstraction to the canvas by automatically handling all drawing calls so that all you have to do is placing the images and calling stage.update().
"so that all you have to do is >placing< the images"
"that can be used to draw and >alternate< images >and< render its output" (missing comma, run on sentence, alternate is probably the wrong word, I'd use change or replace.)
"The Stage is >so to say< the bottom-most container." That doesn't make any sense to me, I'm Canadian so maybe it is a saying elsewhere but I've never heard "is so to say".
Thank you all in advance :)
