WebI have a custom bitset class implementation in C++. I often iterate over the indexes of bits that are set in the bitset (i.e. for bitset '10011' I want to iterate over numbers 0, 3, 4.) WebIterator Interface. A BitSet object is iterable. The iterator gets all bits up to the most significant bit. If no bits are set, the iteration stops immediately. let bs = BitSet.Random(55); for (let b of bs) { console.log(b); } Note: If the bitset is inverted so that all leading bits are 1, the iterator must be stopped by the user!
