In one of the examples, the author fetches results from Firebase, and then sorts them in the browser. I'm not huge on Firebase, but aren't there methods ([0]) to do this on the database, where it'd be much faster and wouldn't waste client cpu?

If this is the case, then this is a bit of faulty abstraction - your database queries are going to be more than just 'select * from <>'. I'm sure there's a way to accomplish this with react hooks without sacrificing elegance for performance.
