They work like array methods — without creating intermediate arrays.

✨ map(), filter(), reduce()
✨ drop(), take(), flatMap()

Iterator - JavaScript | MDN

An Iterator object is an object that conforms to the iterator protocol by providing a next() method that returns an iterator result object. All built-in iterators inherit from the Iterator class. The Iterator class provides a [Symbol.iterator]() method that returns the iterator object itself, making the iterator also iterable. It also provides some helper methods for working with iterators.
