Polyglot Integration

When you need to call Rust from Python, integrate a C++ library into Node.js, or expose Python ML models to other services, this gets you there with FFI, native bindings, or gRPC. The reference guides cover real implementations: Node.js native addons in C++, PyO3 for Rust/Python, Py4J for Java/Python, and gRPC for service-to-service polyglot setups. The best practices are practical,handle serialization carefully, don't pass complex objects across language boundaries, watch for blocking calls in async contexts. It's the skill to reach for when you're combining languages because each does something better than the others, not just because you can.
