A buddy of mine has actually been working on implementing
array producers/consumers as a library, and I think that's a good solution.
i.e. iterators are a nice native addition that can power functionality like
this in userland, and library authors can create libraries to make it
easier to use in userland.

A quick google search shows me that there are existing libraries that do
this (https://fitzgen.github.io/wu.js/) and what my friend is working on
implements a `collect` method which sounds like the `start` method you
mentioned.

Shameless plug: In the meanwhile, I've been working on a library too that,
amongst other things, gives you lazy evaluated list transformations. I'll
be talking about it at https://zeit.co/day :)

Cheers,
Pranay
