@thi.ng/transducers/swizzle.d.ts

Collection of ~170 lightweight, composable transducers, reducers, generators, iterators for functional data transformations

import type { Transducer } from "./api.js";
/**
 * Transducer which performs value reordering on inputs using provided property
 * order. Accepts arrays or objects as input, but always yields arrays.
 *
 * @example
 * ```ts tangle:../export/swizzle.ts
 * import { swizzle } from "@thi.ng/transducers";
 *
 * console.log(
 *   [...swizzle([3, 0, 2, 1], [[1, 2, 3, 4], [10, 20, 30, 40]])]
 * );
 * // [ [ 4, 1, 3, 2 ], [ 40, 10, 30, 20 ] ]
 *
 * console.log(
 *   [...swizzle([0, 0, 1, 1], [[1, 2, 3, 4], [10, 20, 30, 40]])]
 * );
 * // [ [ 1, 1, 2, 2 ], [ 10, 10, 20, 20 ] ]
 *
 * console.log(
 *   [...swizzle(["z", "x"], [{x: 1, y: 2, z: 3}])]
 * );
 * // [ [ 3, 1 ] ]
 * ```
