I have made a very small game in Javascript months ago. I want to do Game programming. What kind of programming I can do to make my skill better.

So for now someone guide me. I am looking for make my skill so I can build my career. For game programming I need your help.

For greatest reach, Adobe AIR / Flash are your best bets. You'll find it very easy to pick up ActionScript (especially after working with JS), and you don't have to worry about portability or compatibility. Of course, performance will always be just a smidge below native code, but then again so will Java and JavaScript (AIR / Flash use many optimization techniques like JIT compilation these days so they're on par in terms of speed).
