GraalJS also runs on the reference implementation, just at reduced
performance compared to running it on a Graal VM:

  "As GraalVM JavaScript is a Java application, it is possible to
  execute it on a stock Java VM like OpenJDK. When executed without the
  GraalVM Compiler as optimizing compiler, performance of GraalVM
  JavaScript will be significantly worse. While the JIT compilers
  available on stock JVMs can execute and JIT-compile the GraalVM
  JavaScript codebase, they cannot optimize it to its full performance
  potential. This document describes how to run GraalVM JavaScript on
  stock Java VMs, and shows how you can use the GraalVm Compiler as JIT
  compiler to guarantee best possible performance."

I think GraalJS also has the advantage that it supports ES6 and newer.
