Function recurrent

Generate a sequence with a recurrent relationship by applying a function to the previous state. Similar to accumulate but generates a new sequence from scratch.

import { pipe } from "yta";
import { map, recurrent, take, toArray } from "yta/async";

await pipe(
  recurrent(([a, b]) => [b, a + b], [0, 1]),
  take(11),
  map(([a]) => a),
  toArray(),
);
// => [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]
Copy
