Methods
bindEventListener
▸ bindEventListener(eventTarget, event, listener, useCapture?): void
Registers the provided event listener to be executed when the specified event occurs on the specified event target.

eventTarget | EventTarget | The event target. |
event | string | The name of the event. |
listener | (event: Event) => void | The event listener. |
