Are you thinking of doing NodeJS? If you are thinking of converting to NodeJS and doing a pull request, we can think of it.

NodeJS is a completely different engine. It uses the V8 engine. ScriptCraft uses the embedded engine in the JVM - either Nashorn or Graal VM.

This is a rare case where I will mention Grakkit as an alternative to ScriptCraftJS. Grakkit is built over GraalVM and can easily integrate with Node.

Technically it's possible to integrate. There is little to no chance of ScriptCraftJS ever getting built-in integration with node. And I dare say no chance at all of rebasing ScriptCraftJS over Node, because as @jwulf said, it's completely different.
