6 Async JavaScript Patterns That Prevent Partial Failures in Production | EndigestGet the latest tech trends every morning

This article covers 6 async JavaScript patterns that prevent partial failures and production bugs in multi-step workflows.
- •Compensated steps: wrap sequential awaits in try/catch with explicit rollback logic (e.g., refund payment if shipment fails)
- •Early promise initiation: start independent async calls before awaiting others to reduce total latency
- •Promise.allSettled over Promise.all: allows partial data rendering when one of multiple API calls fails
- •Selective retry with exponential backoff: only retry on 5xx/network errors, not client errors, to avoid hammering APIs
- •AbortController for stale request cancellation: abort previous fetch on re-render to prevent race conditions in search/query flows
•
Concurrency limiting: process batches with a worker pool instead of firing all requests simultaneously to avoid rate limiting
