Error Handling in Async Code

What error collection pattern is demonstrated?

const results = await Promise.allSettled([
  riskyOperation1(),
  riskyOperation2(),
  riskyOperation3()
]);

const errors = results
  .filter(r => r.status === 'rejected')
  .map(r => r.reason);

Error suppression
Error transformation
Error aggregation
This shows error collection using Promise.allSettled: 1) Collects all errors without stopping on first failure, 2) Allows processing both successes and failures, 3) Maintains operation independence, 4) Enables batch error handling, 5) Useful for parallel operations where all attempts matter, 6) Common in scenarios requiring comprehensive error reporting.
