Can you assign a new array to a `ref` holding a list?

const items = ref([]);
items.value = await fetchItems();

✓Correct answer: Yes - replacing .value is tracked, and in-place mutations like push are tracked too
2No, refs can only hold primitives
3Only with items.set(newArray)

Explanation

Vue 3's Proxy-based reactivity tracks both replacing the value and mutating arrays (push, splice, index assignment). This was a known limitation in Vue 2 that is gone now.
