javascript is clearly the most popular and widely used programming language in history. c/c with classes has the most software built on top of it, putting them at the most important languages on opposite sides of the software stack.
what would be interesting is a back of the envelop calculation on # lines of js vs c executed globally per minute. id guss c probably wins due to frequency of execution.
Considering the fact that every line of js you execute is run in a VM that is implemented in c/c-with-classes I am guessing this will not really be much of a contest... :)
And on an OS mostly/entirely written in C. For most software out there I'd imagine C was used somewhere in that stack. The same can't be said about JavaScript.
That said, I bet JavaScript use will increase and C will shrink, relatively speaking.
