Yeah, I'm missing something. It's the difference in code between: ```js var newMap = oldMap.map(([k, v]) => [k + 1, v + 1]); ``` versus ```js var newMap = new Map(oldMap.entries().map((([k, v]) => [k + 1, v + 1]); ``` I think I still prefer avoiding every iterable subclass adding its own map/filter/etc. in favor of people using the compositional base primitives, but at least I see the argument now.
