Last year at JS Kongress in Munich there was a Deep Track (aka unconf) and Marja Hölttä gave a talk about WeakRefs. In the middle of her talk a very loud noise appeared from the window. So loud no one can hear Marja and she paused. That was a garbage truck, which drove behind the window. When it left, someone broke the silence saing “garbage collection ¯\_(ツ)_/¯”. That was funny.
