I am currently working on a liking feature for posts, as well as replies and shares. Whenever I hit like then hover the liked button, all liked posts show the heart broken icon indicating if a user wants to dislike a certain post - how can I fix this so only the post that i hover over shows the heart broken icon versus all posts showing it?
My code in question:
{(Object.values(state.posts)).length !== 0 ?
<InfiniteScroll height='100%' dataLength={numberOfPosts.length} next={fetchMoreData} hasMore={hasMore} loader={<Loading style={{position: 'absolute', left: '50%'}}/>}
id='all-post-container' scrollThreshold={0.5} endMessage={<p style={{ textAlign: "center" }}>
<b>That's all folks!</b>
</p>}

useEffect that expands the 'like' array when numberOfPosts changes:
useEffect(() => {
setLike(numberOfPosts.map((_, i) => (state.posts[i].likedBy.includes(state.storage.id) ? true : false)));
}, [numberOfPosts])
