Svelte · Middle · Question 7 of 75

When is `$state.raw` a good choice?

let rows = $state.raw([]);
rows = await fetchRows(); // reassign, don't push

✓Correct answer: For large objects or arrays that are replaced as a whole (like API responses), to avoid proxy overhead
2For values that must never change
3For state shared with the server

Explanation

Raw state isn't deeply reactive: rows.push(x) won't trigger updates, only reassignment does.
