Second one is performance for numerical computing, followed by modules, generics, OOP and almost forgot that one, better type safety.

While reading the blog article, I kept wondering what the performance was like compared to bare metal?

I guess the performance hit is similar to the one C and Rust take? In the order of 10x slower IIRC? How does a Fortran-written (better optimized) library compare to a C-written one? Is the WASM overhead enough to nullify the performance difference? Are the original optimizations well translated to WASM?
