What are the best practices for using event emitters in Node.js?

Some best practices include: 1) Use meaningful event names, 2) Limit the number of listeners, 3) Clean up listeners when no longer needed.

Can you explain why it's important to limit the number of listeners?

Limiting listeners helps prevent memory leaks and ensures that your application remains performant, especially under heavy load.

What should I do if I need to emit events frequently?

If you need to emit events frequently, consider batching events or using a throttling mechanism to manage the load.

Are there any libraries that can help with event emitters?

Yes, libraries like EventEmitter3 and Node's built-in EventEmitter are great options that provide additional features and optimizations.
