I don't see that as the case. Modern JS can do a lot out of the box but the culture looks down on "vanilla" JavaScript. I've seen way too many libraries that are nothing but a thin wrapper around native functionality. When your first (and only) technique is to look for a library, this is where you end up.

I agree and am very pro vanilla JS FWIW. I just find myself reaching for something like lodash's `intersection`/`difference` functions when working with sets, `sortBy` to get more normal (and not in-place) sorting behavior, and `groupBy` to do group by.
