Language for web game development

I've been making arcade-style flash/java games long enough I've started to make a living off of it, despite not knowing alot about what I'm actually doing coding-wise.
I've pretty much been using java the most to make games as it seems the more mature of the two and has tons more advantages over flash.
Now I'm thinking of starting a commercial online game but I'm wondering if there's any language better than java to do this.
Is there any better language that can be used to make games, compile them and embed them into a web-page(crucial)?

Silverlight is a piece of shit. It's Microsoft's six-years-too-late answer to Flash, it doesn't have even a hundredth of a percent of the testing Flash has benefited from over the years (and Flash is STILL buggy). Plus, it only runs on Windows, and even there, it probably won't be installed on most client systems (like Flash is), so you'd be shutting out a large portion of your potential target base by using it.
