Does Rayon use iterators, or just iterator-like combinators? I don’t think a for-loop would work with Rayon, would it? You can also definitely implement iterators using first-order functions: const iterate = array => { const step = index => ({ value: array[index], next: () => step(index + 1) }); return step(0); } // add some combinators on top First order functions can in fact implement anything if you’re willing to accept some bad syntax and speed — that’s the Church-Turing equivalence.
