Answer
Use try/catch for async/await or .catch() for promises.
Differentiate between:
- Network errors
- HTTP status failures
- Logical/validation errors
Quick Answer
Handle API errors at multiple levels: check response.ok in fetch (HTTP 4xx/5xx don't reject), catch network errors in .catch(), use try/catch with async/await, show user-friendly error UI, log errors to a monitoring service. Pattern: distinguish between retriable errors (network timeout), client errors (400 — fix the request), and server errors (500 — retry or notify).
