-Iterator helpers are a collection of new methods on Iterator prototype (*Iterator helpers*) that help in general use of iterators. Since these helper methods are on the iterator prototype, any object that has Iterator.prototyype on its prototype change (e.g. array iterators) will get the methods. In the following subsections, we explain these introduced helpers. All the provided examples are working in a blog archive page that includes list of blog posts, illustrating how iterator helpers are helpful for finding and manupulating posts.

-`reduce` takes a reducer function and an optional initial value.

The initial value is used as the starting point for the reducer function when it processes the first item of the iterator.

 ## Iterator.from(object)
 
-`from` is a static method and takes an object as an argument. If the `object` is already an instance of Iterator, the helper returns it directly. If the `object` has @@iterator (is an iterable), its @@iterator method is called to get the iterator and the helper returns it. Otherwise, a new Iterator object (that inherit from Iterator.prototype and has `next()` and `return()` methods) is created that wraps the `object` and is returned by this helper.
