Best language to learn for...
I am interested in what the best language(s) to learn for browser based hacking. I've dabbled here and there with programming, but I never really got into it because I had nothing to actually apply what I was learning too (at the time I was helping with an ABer, but it got scrapped a month in because the website closed). Now that I'm here I want to get back into it so I can make contributions to the community the only problem is I'm not sure which language I should make a go at when it comes to game hacking.
Suggestions?
