This channel deserves more views, I see all of this garbage tutorials, where for 20 min they say nothing, but get 100k views, because they farmed more subs

There's one important detail missing, WeakMaps allow for garbage collection, meaning if a key is no longer in use it will be, well, garbage collected. This is the main use case since Maps aren't subject to garbage collection.
