I don't know what this table is supposed to measure but it doesn't check out.

(C, C++) and (JS, TS) are almost source-compatible, chances are you can rename test.c to test.cpp and test.js to test.ts and you're done. Yet they're showing massive differences?

Also most of the compiled languages with no runtime should get results that are very close to each other: good compilers should produce similar object-code for this type of microbenchmark.

Not to mention this is really measuring the implementation, you can't measure a language. Mike Pall wouldn't be down there, and JS/TS wouldn't be up there without V8 and friends.

I imagine you would want to test "idiomatic" code for these comparisons. It doesn't make much sense to compile with C++ and write everything in C.
