Agreed, it's not a very well labeled article. 'Programming Languages most submitted to CodeEval in 2014' would be better.
Consider the talk around wearables. Most wearables would be small devices running a bit of code. Maybe some of them will be hackable. Are the current generation of wearables powerful enough to run anything other than C (or maybe C++)? Nope. That's because most would be either small microcontroller or small ARM devices. If you take that trend and the fact that codeeval says its javascript - makes no sense.
So, submissions in codeeval should be title for sure.
