Web Assembly for Java Developers

on YouTube ↗28m

" summary

Explains practical Java routes to run WebAssembly: use Wasmtime Java (a JNI wrapper) or the higher-level plugin SDK that exchanges JSON and enforces sandboxed memory/time limits, or use the new shikui pure-JVM runtime to avoid native libs. Demonstrates Doom runs in interpreter mode on the JVM with zero native dependency and promises near‑native speed once JIT lands. Notes serverless use (millisecond/microsecond cold starts), WASI for syscalls, and JSON-based host-plugin APIs.
