Is it stupid to just (hash a-bunch-of-things) if I want to trigger the effect to re-run whenever a-bunch-of-things change?

IIRC there are times when hash will return a different number for the same value. it would be ideal for something that's best effort

what's stopping you from using a-bunch-of-things instead of hashing it?

I thought React won’t do a deep compare in that case?

it does not, that's correct

does a-bunch-of-things change every render?

No, it doesn’t change often. But I’m now realizing that hashing is probably the same as using the thing directly

if the reference identity is stable, then I would just use the thing directly

e.g.

(def a-bunch-of-things [1 2 3 4])

where you run into issues is if you have something like this inside a render:

(let [a-bunch-of-things [1 2 3 4]]
  (react/useEffect
    #(do-thing)
    #js [a-bunch-of-things]))
