Function zip

Take any number of iterators, and zip them together into one iterator of tuples. Closes after the shortest of the inputs closes.

import { pipe } from "yta";
import { flatRepeat, of, range, toArray, zip } from "yta/sync";

pipe(
  zip(
    of("a", "b", "c"),
    range(),
    flatRepeat(() => of(true, false)),
  ),
  toArray(),
);
// => [["a", 0, true], ["b", 1, false], ["c", 2, true]]
Copy

If you want to zip an iterator of iterators in a pipeline you can use them spread opperator.

import { pipe } from "yta";
import { flatRepeat, of, range, toArray, zip } from "yta/sync";

pipe(
  of(
    of("a", "b", "c"),
    range(),
    flatRepeat(() => of(true, false)),
  ),
  (iterables) => zip(...iterables),
  toArray(),
);
// => [["a", 0, true], ["b", 1, false], ["c", 2, true]]
Copy
