Common Error Handling Patterns
Increase delay between retries: 1s, 2s, 4s, 8s...
setTimeout(() => retry(), Math.pow(2, attempt) * 1000)Stop retrying after repeated failures to prevent system overload
if (failureCount > threshold) return fallbackContentProvide alternative content when primary loading fails
@error { <fallback-component /> }
