Except we've become so used to loading multiple megabytes of JS even on a simple blog post, that a 30KB library probably won't make a noticeable difference. Insofar as file size is concerned, I'd much rather pull in jQuery than some random npm package that depends on god-knows-how-many other random packages.

Even GOV.UK, an incredibly lean website by today's standards, only noticed a 10% difference in their benchmarks.
