dyn.js - 100% invokedynamic JavaScript implementation

on YouTube ↗28m

" summary

Claims a Java 7 invokedynamic on JVM JavaScript runtime called gjs (dyn js) that links dynamic calls via Dynalink/method handles, removes massive glue code, and generates bytecode with a small internal DSL for an AOT-style per-function compiler. It currently implements ES3 parsing, prototype chains and autoboxing, exposes a disassembler repo and debug dumps, and is early work in progress — not spec complete — with early runs stated as roughly 4–8× faster than JRuby on some workloads.
