We have added a port of V8 (home site, Wikipedia), an open source JavaScript engine developed by Google, to complement the other scripting language runtimes on the PlayBook. V8 ships with the Google Chrome web browser and other frameworks such as Node.js. Version 3.8.9 has been ported to the BlackBerry Native SDK and is publicly available on GitHub here: https://github.com/blackberry/v8.
Instructions for building on both Linux and Mac OS X are included in the repository README file. The native PlayBook web browser does not use V8 as it’s JavaScript engine.
