Example of implementing retry logic for transient errors (5xx status codes) using JavaScript.

```APIDOC
## Error Handling Strategies

### 1. Retry Logic

Implement retry logic for transient errors (5xx status codes):

```javascript
async function apiCallWithRetry(url, options, maxRetries = 3) {
  for (let attempt = 0; attempt < maxRetries; attempt++) {
    try {
      const response = await fetch(url, options);

      if (response.ok) {
        return await response.json();
      }

      // Don't retry client errors
      if (response.status >= 400 && response.status < 500) {
        const error = await response.json();
        throw new Error(error.message);
      }

      // Retry server errors
      if (response.status >= 500) {
        throw new Error('Server error');
      }
    } catch (error) {
      if (attempt === maxRetries - 1) {
        throw error;
      }

      // Exponential backoff
      const delay = Math.pow(2, attempt) * 1000;
      await new Promise((resolve) => setTimeout(resolve, delay));
    }
  }
}
```
