is there a way we can remove a event listener

[aster2709]

say i have a listener to listen to events:

await contract.on(filter, ...)

how can I stop the listener. I am not willing to kill the process. I'm trying to use it in a node backend where I can start and stop listening to events via express api.

It follows the normal JavaScript event emitter API, so you can use contract.on(filter, listener) to start listening and contract.off(filter, listener).
