What ECMAScript version is used by versions 16++ (UXP, "New World")?

[KlausKi]

I read this three year old article about UXP "New World" replacing the existing ExtendScript engine in Adobe products.

When I'm writing code in VS Code with version 2.0.0beta2 - 2022-02-14 of the ExtendScript Debugger extension, it still looks like the "old" ExtendScript engine is used.

How can I make sure the new engine is being used when writing scripts for Adobe products?

Moved this here where you'll get an answer from the author of the article.

Hopefully, the fact that we've entirely disabled the Old World, should build confidence. 🙂 

The debug flag that disables New World, is now a no-op.

The question has nothing to do with Acrobat and PDF.
