removeEvent
RemoveEvent is a general term used in event-driven programming to describe the act of unregistering a previously attached handler from an event source.

The specific function or method that implements this behavior varies by platform, but the core idea is the same: supply the event type and the exact listener to remove, and the binding is broken.
In browser environments that implement the standard DOM EventTarget interface, this is performed with removeEventListener(type, listener,
In older browsers based on the legacy IE event model, detachEvent(type, handler) was used. It required the
In Node.js, EventEmitter exposes removeListener(eventName, listener) and, in newer APIs, off(eventName, listener) as an alias. A
Best practices include keeping references to handlers, avoiding anonymous functions for easily removable listeners, and performing
