The code imports the Node.js os module and uses its hostname() function to retrieve the hostname of the system.

The code imports the Node.js os module, which provides information about the operating system. It then uses the hostname() function on the os object to retrieve the hostname of the system.

What the code could have been:

import * as os from 'os';

/**
 * Retrieves the hostname of the current system.
 *
 * @returns {string} The hostname of the current system.
 */
function getHostname(): string {
  try {
    // Use os.hostname() to get the hostname
    const hostname = os.hostname();
    if (!hostname) {
      throw new Error('Hostname not found');
    }
    return hostname;
  } catch (error) {
    // Handle any errors that occur
    throw new Error(`Failed to retrieve hostname: ${error.message}`);
  }
}

// Example usage
try {
  const systemHostname = getHostname();
  console.log(`Hostname: ${systemHostname}`);
} catch (error) {
  // Handle any exceptions
  console.error(`Error: ${error.message}`);
}
