const [covidConnectResults, loading] = useFetch({ city: searchStr, materialType: resourceType });
const removeDuplicateTweets = () => {
    const memo = {};
    const filteredResults = covidConnectResults.filter(result => {
        if(!(result.full_text in memo)) {
            memo[result.full_text] = true;
            return true;
        }
        return false;
    });
    return filteredResults;
}
const covidTweetResults = removeDuplicateTweets(covidConnectResults);

return <></>

and here,
covidConnectResults={covidTweetResults}

Instead of having a state and updating it, can we have a the simple filter function before it going to component ?
This is because already while typing, for each letter it renders the component. Having another state inside the component double the render. 🤔

Just my opinion 🤔 Can we do the above ?👆
