That's exactly what I'm trying to change. JavaScript should be the right tool for that level of performance. It has JIT compilers, now it needs concurrency, and it'll perform with the best of them.
If you're trying to push Javascript to its limits and make it comparable to C++, good for you. Just remember that JS has many flaws.If you're going down that road I'd much prefer you give the world a Turbo javascript that comes with an IDE like Turbo C and the requisite documentation that all fit on a single 1.44MB disk and which can compile to directly executable code that doesn't need any runtime.
