IMO: no. First of all, I love JavaScript, and I think it could be used for far more than it currently is. Having said that, it is not good for every problem, due to limitations of the language itself. It is not multi-threaded. It is not good for CPU-intensive operations (transcoding video, encryption tasks, etc.) It does not allow direct access to memory. I still love it, and it is closer to being a universal language than most people think, but I also believe that the designed limitations are still an issue.
