How to parse YAML inside a user script

[jrsmith3]

I have written a user script in which I need to parse some YAML-formatted text that gets passed in via a function argument. I know I can pass the tp object into the function to access tp.obsidian.parseYaml, but I would like to know how to do this without the tp object.

Note that this YAML is not note frontmatter, I've extracted it from the body of the note itself.

FWIW, I'm primarily a Python developer and not a JavaScript dev. Thanks.
