The article says that

    items = items.filter(i => i !== item);

is compiled to

    $$invalidate('items', items = items.filter(i => i !== item));

So this invalidates the whole array, right? Would this then re-render the whole array, i.e., remove and recreate all DOM nodes? And if so, does Svelte support more fine-grained ways to update arrays?
