shuffle() function

Fisher-Yates アルゴリズムを使用して、入力配列の要素をランダムにシャッフルした新しい配列を返します。

Signature:

declare function shuffle<T extends Iterable<unknown> | AsyncIterable<unknown>>(
  iterable: T,
  seed?: number,
): ReturnArrayType<T>;

Example

shuffle([1, 2, 3, 4, 5]); // [3, 1, 5, 2, 4] (random order)
shuffle("hello"); // ["o", "e", "l", "h", "l"] (random order) Only ASCII codes are shuffled in the case of a string.
shuffle([1, 2, 3, 4, 5], 42); // [2, 4, 1, 5, 3] (deterministic with seed 42)
