I was talking about Javascript, not Typescript. Those are different languages. I write all my fronzend code in Typescript too, because it has a very nice type system. But it has other flaws. E.g. always infering tuples as sum typed array.
I also would not write a Backend in C++ but I would like it more than a Javascript backend.
And yes JS is the fastest of the scripting languages, but if you achieve 10x speedup with something that was 100x slower, it is still slow.
Also is Javascript horrible on a multi core CPU as it cant use it fully.
10x is the worst case - you would typically get around 2x-3x worse performance compared with most compiled languages. See for example benchmarksgame.alioth.debian.org/u... - and thats with 4 cores vs 1 core for most of the programs. When limited to single core the difference is even smaller.
