I remember trying to do this with jQuery and localstorage, and was amazed it work, but so frustrated the many times it broke or caused issues. Built an entire shopping cart w/ a team in jQuery and localStorage as the store with some handlebar templates. In retrospect it was horrible code. This was in 2015 though, so react/vue were less wide spread and I was much more junior.

Now it's so much better/easier to use Vue, or react or even Svelte or the smaller similar stacks like alpine, htmx, etc that at least make state management easier than it ever was dealing with jQuery. the only thing jQuery had going for it was the ease of using selectors, honestly I think a jquery lite package that just has all the selector stuff would be nice, I sometimes forget all the document.getElementById stuff, but $('#id') is a much (imho) better syntax anyways. There probably already exists something like that - haven't looked but maybe I will later now that my interest is piqued.
