Re:Gov.uk drops jQuery from their front end

It adds tens of milliseconds to just downloading on a fast connection, plus it has to be parsed before what ever you need it to do will be functional.
To compare, just roughly:
For roughly the same size you can get declarative/reactive rendering with React, or an optimized FP standard library with ClojureScript, or data driven visualizations with d3 (roughly 2x the size).
For a tenth of the size you can get stuff like htmx, or a json validation library (avj), or like someone said Preact (React alternative).
But for jQuery, you're paying that for basically nothing the browser APIs don't already provide. It was a godsend 10y ago, but with legacy browsers finally fading out, the last one being ie11, you really don't _need_ it anymore.
