How can I optimize event emitters in my application?
To optimize event emitters, consider reducing the number of listeners, using weak references, and batching events.
What are weak references and how do they help?
Weak references allow the garbage collector to reclaim memory if there are no strong references, preventing memory leaks.
Can you explain how to batch events?
Batching events involves grouping multiple events together and emitting them at once, reducing the overhead of multiple calls.
Are there any libraries that can help with this?
Yes, libraries like EventEmitter3 and Node.js's built-in EventEmitter can help with optimized event handling.
