Web Inspector neatly shows upcoming values for native iterators.
https://webkit.org/blog/3516/web-inspector-console-improvements/
Unfortunately, it doesn't do it for developer defined iterators.

Custom data structures such as linked lists, ordered sets, ordered maps, 
sorted arrays and many others that you can find in Immutable.js[1]
and Collections.js[2] would benefit from better console logging.

Web Inspector could show upcoming values for all objects that have
Symbol.iterator property.
