Wait, wait. I'm trying to make friends with React for less than a month and I do appreciate this article giving me some understanding about the primitives react gives me and when to use it (Or how you called it screws/nails)
I did understand more, but I'm left with a feeling I cannot follow the "flow" of the useEffect as I couldn't understand how can items !== prevItems EVER be true?
// Better: Adjust the state while rendering
const [prevItems, setPrevItems] = useState(items);
if (items !== prevItems) {
setPrevItems(items);
setSelection(null);
}
useState doesn't return immediatelly? Or does it cause immediate re-render? I kind of gathered from the article that all useState calls cause re-render whenever it encounters return.
