filteredBanks state is not updating
banks is a grandparent state which has a lot of objects, similar to that is filteredBanks whose set method is being called here which is setFilteredBanks
if I add a console log and save or remove it the state updates
Adding or removing the console statement and saving the file, renders the function again, the internal function's state is updated returned with the (setState) callback.

Adding filteredBanks to your dependency array won't do much because it is part of the lexical scope of the function searchBanks
I'm not entirely sure of the total context of this BankSearch or what it should be. What I do see is that there are some antipatterns and missing dependencies.
Try this:
export default function BankSearch({ banks, searchCategory, setFilteredBanks }) {
const [searchString, setSearchString] = useState();
const searchBanks = useCallback(
search => {
const filteredBanks = [];
banks.forEach(bank => {
if (bank[searchCategory].toLowerCase().includes(search.toLowerCase())) {
filteredBanks.push(bank);
}
});
setFilteredBanks(filteredBanks);
},
[banks, searchCategory, setFilteredBanks]
);
const debounceSearch = useCallback(() => _debounce(searchBanks, 500), [searchBanks]);
useEffect(() => {
if (searchString?.length) {
debounceSearch(searchString);
} else setFilteredBanks([]);
}, [searchString, searchCategory, setFilteredBanks, debounceSearch]);
const handleSearch = e => {
setSearchString(e.target.value);
};
return (
<div className="flex">
<Input placeholder="Bank Search" onChange={handleSearch} />
</div>
)}
It feels like the component should be a faily simple search and filter and it seems overly complicated for what it needs to do.
Again, I don't know the full context, however, I'd look into the compont architecture/structuring of the app and state.
