If you already know python and JS I think you probably won't have too much trouble with Nim, but why not add something new like memory management to learn about? Rust is complicated, but it has training wheels, and its wasm support would integrate with your JS knowledge. Alternatively modern C is still used everywhere and will teach you a lot about hardware.

You can learn that with Nim too. It supports manual memory management like C. The new ARC/ORC GC also works more like modern C++ than a traditional GC.

Nim can also compile to JS. Or you could compile it first to C and then compile that to wasm, although that's not supported out of the box.

Those are good points. I have found that languages that don't force me to use a feature don't teach aa well as ones that do. I usually don't want to use those languages later though ( java and oop or Haskell and functional) because I like having options. Nim gives you lots of options it sounds like.
