Re:  ECMAScript 2020 and GraalVM

https://github.com/graalvm/graaljs

https://www.graalvm.org/

"GraalVM JavaScript is compatible with the ECMAScript 2020 specification
<http://www.ecma-international.org/ecma-262/11.0/index.html>. "

Based on OpenJDK 8 and 11

GraalVM may be a path forward for NetBeans?

Excellent!
