Aaaand this works on arrays, but would you know how to make it work for files? You would need to do something like how the essay wrapped the `rdr` into a sequence, but it would still require (probably) the whole data to be present in the memory at once... I think you would need something like this: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... but I found it quite mind-bending when I tried it once. Clojure's way of building something like this out of a `lazy-seq` call feels simpler to me...
