function product
product<T extends unknown[]>(
iterables: [K in keyof T]: Iterable<T[K]>,
repeat?: number,
): Generator<T>

Generates the Cartesian product of input iterables.

Examples

Example 1

import { assertEquals } from "@std/assert";

const sequences = [...product([[1, 2, 3], [4, 5, 6], [7, 8, 9]])];

assertEquals(sequences, [

  [1, 5, 7], [1, 5, 8], [1, 5, 9],
  [1, 6, 7], [1, 6, 8], [1, 6, 9],
  [2, 4, 7], [2, 4, 8], [2, 4, 9],
  [2, 5, 7], [2, 5, 8], [2, 5, 9],

  [3, 6, 7], [3, 6, 8], [3, 6, 9],
]);
