Welcome @speed4! 👋
Sorry you ran into a spot of trouble.

The syntax-tree packages are designed to run on Node.js 16+.
It can also be compiled to target the web, for a web target it should work on recent versions of evergreen browsers.

Chrome 42 is over 8 years old now, and hasn't been supported in years.
My suggestion would be upgrade your Chrome version, it is very insecure.

If you still want to try to make things compatible with unsupported browsers.
You are welcome to try out various transpilers like babel and swc, and polyfills like core.js.

Understand that Chrome 42 isn't a target/supported platform of unist-util-parents, so this isn't a bug.
