I'm a fan of construct 2. It's quick to get started, easy to use, flexible (can make any type of 2D game), fast (as javascript goes, anyway - using webgl for improved framerate as well), does a lot for you (minimizes garbage creation automatically to minimize/mostly eliminate garbage collection pauses by the browser), has a lot of options for export (phonegap, they're working on appmobi's directcanvas for improved rendering speed on mobiles, facebook, kongregate, chrome web store), is updated every week or two with a new version, has a very friendly community and active forum, and is frankly a ton of fun to use.

There's a free version as well if you want to try it out and see what you think.
