Error Handling in Async Code

What error handling scenario is being addressed?

async function fetchWithTimeout(url, ms) {
  const controller = new AbortController();
  const timeoutId = setTimeout(() => controller.abort(), ms);
  try {
    const response = await fetch(url, { signal: controller.signal });
    clearTimeout(timeoutId);
    return response;
  } catch (error) {
    clearTimeout(timeoutId);
    if (error.name === 'AbortError') {
      throw new Error(`Request timed out after ${ms}ms`);
    }
    throw error;
  }
}

Timeout handling
This handles timeout scenarios in async operations: 1) Implements controlled timeouts for async operations, 2) Properly cleans up resources, 3) Transforms abort errors into meaningful timeout errors, 4) Preserves original errors for non-timeout cases, 5) Uses AbortController for proper cancellation, 6) Essential for preventing hanging operations in network requests.
