Yes. Is that so weird? JS is also performant when you don’t use JS considering you’re running it on C or Rust and are likely using the FFI if you’re doing any form of computation heavy work.
Yes, it's very weird. When I write JavaScript, I expect it to run reasonably fast because of the JIT - and it does. I've never felt the need to use FFI, and libraries that use it generally do so because they want to interact with pre-existing C or C++ code, not because it's the only way to get decent performance.
