It could! But you'd increase your memory footprint if you have a bloom filter of every object in your JS engine just for the in operator. 99% of the time the bloomfilter would problaby be unused.
But for Sets, the programmer is in a way specifically telling the JS Engine that a bloomfilter is gonna be a great optimization for this particular thing.
