But how would you generalize that for a resume?

I separate languages and tools/frameworks (not a dev CV so take with a grain of salt). No clue about the c# world, but for js I’d do something like:

Languages: js, TS

Frameworks: express, react, etc.

The key is to hit all of the required keywords, machines and HR don’t know anything else. If a developer looks at your résumé they’ll know that you wrote both ends.
