Hammer.js for Angular 2+

[VladislavLobakh]

I use hammer.js in my applications (Angular 2 and 5). I use events from this library, as example - tap. If I destroy any DOM-element with the help of *ngIf, there's subscription on the event. As a result, there's a reference to the DOM-object in the memory.

Example

How I can remove listener from this DOM-element?

without tap
with tap

Using it with Angular, too and didn't know about this. Anyway wouldn't this be the same on normal plain js usage? If you remove the dom-element the reference will stay? Could you make a comparison with plain JS or jQuery?
