1. TIL that the max size of a Map/Set is 26843544 Nov 11, 2022 javascript mdn v8 math

   JS Maps and Sets are implemented by OrderedHashTable. OrderedHashTables double in size when they need to grow, and their max size is 26843544. After 16777216 elements, doubling that exceeds the max, so the allocation fails.Currently these data structures are not implemented to be usable for large in-memory datasets. Also note that the JS specification itself doesn't require that Maps and Sets must scale with available memory.
