What happens when an iterator's next() method returns an object with done: true?
- It means the iteration is complete, and further calls to next() will throw an error
- It indicates an error in the iteration process
- It signals an infinite loop in the iteration
- It signifies that there are more elements to be iterated
When the next() method returns an object with done set to true, it indicates that the iteration has reached its end, and there are no more elements to be processed. Subsequent calls to next() will continue to return objects with done: true, providing a clear signal that the iteration is complete.
