Game and web developer specializing in Javascript and Actionscript.
I ported the Ash entity-based framework over from Actionscript to Javascript.
You can get it from github: https://github.com/brejep/ash-js. It is a really nice entity system, originally designed and implemented in Actionscript 3 by Richard Lord. The original can be found at: https://github.com/richardlord/Ash.
