I agree the JS standard library includes most of the stuff you need these days, rendering jquery and half of lodash irrelevant now. But there's still a lot of useful utilities in lodash, and potentially a new project could curate a collection of new, still relevant utilities.
It was more useful before when browsers didn't support array.map and fromEntries. That's the origin of all these libraries, but browsers caught up. Things like keyBy, groupBy, debounce, uniqueId, and some others, are still useful.
