Please, tell us what's the problem?

Wrong documentation

Please, tell us more details

Hi! I found a super weird example in the docs https://docs.nativescript.org/core-concepts/events#working-with-weak-events-Adding

• this uses in global scope (it's undefined)
• addWeakEventListener has a totally different definition: addWeakEventListener(source: Observable, eventName: string, handler: (eventData: EventData) => void, target: any): void;
• no WeakRef import
• there are no WeakEventListener and WeakEventListenerOptions exports in the tns-core-modules/ui/core/weak-event-listener-module
• and other mistakes...
