Your nice work on the JS itertools port has a todo for a "better tee". This was my fault because the old "rough equivalent" code in the Python docs was too obscure and didn't provide a good emulation. Here is an update that should be much easier to convert to JS: def tee(iterable, n=2): iterator = iter(iterable) shared_link = [None, None] return tuple(_tee(iterator, shared_link) for _ in range(n)) def _tee(iterator, link): try: while True: if link[1] is None: link[0] = next(iterator) link[1] = [None, None] value, link = link yield value except StopIteration: return
