| name: Iterator methods | ||
| description: The `Iterator` object is an abstract base for objects that implement the iterator protocol. It provides methods common to built-in iterators, such as `filter()`, `find()`, `map()`, and `reduce()`. You can also use the static method `Iterator.from()` to convert an existing iterable into an `Iterator`. | ||

Just for posterity: I wondered by
javascript.builtins.Iteratorwasn't included here. Ultimately, I found that it makes sense: BCD tells a half-truth in that all browsers supportIteratorin the sense that they implement iterators. But don't actually exposeIteratoras a defined object, at least not until they shipIterator(). The BCD and MDN docs are extremely confusing on this point.
