Java is the only language I have seen reliably developed from multiple OSs as a team. Even JS fails at this, as plenty of its packages are wrappers over native tools, which more often than not fail to run/run the same way on different OSs. Java on the other hand is basically 100% pure, dependencies/tooling doing FFI is very rare
