Polyglot Done Right with GraalVM
summary
GraalVM runs JVM languages plus JavaScript (Node), Python, Ruby, R, WebAssembly and LLVM bitcode and claims near-native speed by using the Truffle interpreter layer and Truffle partial evaluation to inline interpreter nodes into hot machine code. Examples: server-side React rendering from a Java backend, Doom running via the LLVM guest, JR‑CUDA bindings for GPU code, Dutch police embedding R in Scala, and Coherence sharing a cache between Java and Node. Key APIs are polyglot Engine/Context/Value/Proxy API, plus Chrome‑inspector cross-language debugging and optional AOT native images.
