2D Engines for Javascript

I'm attempting to build a tile-based game in javascript, using HTML5 canvas. There are -many- engines to choose from, such as;

• Jaws


• GameJS


• Cocos2D

... and the list goes on and on.

However, there does not seem to be one de facto standard among all these different implementations. Essentially I am looking for the 'jQuery' of javascript game engines. One that is backed by a (larger) community, has excellent documentation and is actively maintained. Most of these just seem like one-man projects to me.

To phrase this into a real question; what is the de facto standard for 2d game engines in javascript?

Additionally I would be very interested in experiences with actual implementations (other than demo pong / pacman games).
