How do I handle connection errors when using `createClient` in Node.js Redis and its options?

You should listen for the 'error' event on the client instance returned by `createClient`. This event is emitted when a connection error occurs. The error object provides details about the issue. Example: `const client = redis.createClient(); client.on('error', (err) => { console.error('Redis error:', err); });` Consider implementing a retry strategy to handle connection issues, and the 'end' event should also be monitored.
