How do you narrow the results of Promise.allSettled?

const results = await Promise.allSettled(tasks);
const values = results.filter((r) => r.status === 'fulfilled').map((r) => r.value);

• ✓Correct answer: Check the status discriminant; since TS 5.5 the filter callback is inferred as a type predicate
• 2Use r.value! everywhere
• 3Results are always fulfilled
