- Garlef 6y agoisn't python fast because it uses specific c++ (or c?) modules in the background? for example keras is a wrapper for tensorflow (c++). numpy relies on c if i understand this correctly.
- hctaw 6y agoI think it's more apt to say that Python isn't fast, but it has FFI that can be used to interface with things that are fast. The same is true of JS though, and most interpreted languages that have an escape hatch for FFI. The difficulty of getting it to work may vary.
- cies 6y agoWe're talking specifically about sci prog here. I think for one the ecosystem is just not there on JS.
