es6-collections-iterators

Adds missing values, keys and entries functions to native es6 collection implementations

This especially concerns Internet Explorer 11, which implements es6 collections, but does not implement the functions to retreive their elements via iterators and Safari 7.1 and 8, which implement the functions but do not return a valid iterator (the next method is missing).

This polyfill tries to fix this to make IE 11 and Safari 7.1 and 8 more compliant with the current standard.

Usage

require('es6-collections-iterators')

Note that this polyfill only does something if the collections Set and Map are available, but the respective prototype methods entries, keys and values are not implemented correctly.
