This mailing list is generally about the API itself, and not really about API client libraries. You'd might get more relevant help on wikitech-l, or a list about MediaWiki's JavaScript libraries if there is one.

I know that there are several MediaWiki configuration values available in JavaScript through the object mediawiki, and I've made use of mw.config a fair bit as necessary. Right now, I want to access the enums for namespaces, such as NS_MAIN = 0 or NS_TALK = 1, from JavaScript. Are these exposed anywhere in the mediawiki object?

You could construct such a mapping using e.g. https://en.wikipedia.org/w/api.php?action=query&meta=siteinfo&siprop=namespaces
