# Event listeners

Event listeners are JavaScript methods that set up a function to run whenever the specified event is delivered to the target.

You can use event listeners to provide UI feedback to your end-users, handle retries, and more. Since custom events do not support callbacks, event listeners give you access to the current status (loading, success, error) of any action carried out.
