shuffle (Functional Programming)

Creates a function that returns a shuffled copy of an array. Use it with pipe.

typescript

const result = pipe(array, shuffle());

::: info

Prefer the original es-toolkit shuffle in ordinary code. Use this fp variant when composing transformations with pipe.

:::

Usage

shuffle returns a new array containing the same values as the piped array in random order. It does not mutate the input array.

typescript

import { pipe, shuffle } from 'es-toolkit/fp';

const values = pipe([1, 2, 3], shuffle());
// values contains 1, 2, and 3 in random order.

This function takes no arguments; call it as shuffle().

((array: readonly T[]) => T[]): A function that maps a readonly T[] to a shuffled copy.
