cycle() function

返回无限重复给定 Iterable/AsyncIterable 的 Iterable/AsyncIterable。

Signature:

declare function cycle<A extends Iterable<unknown> | AsyncIterable<unknown>>(
  iter: A,
): ReturnIterableIteratorType<A>;

Example

const iter = cycle("abc");
iter.next(); // {value:"a", done: false}
iter.next(); // {value:"b", done: false}
iter.next(); // {value:"c", done: false}
iter.next(); // {value:"a", done: false}
iter.next(); // {value:"b", done: false}

// with pipe
pipe(cycle([1, 2, 3, 4]), take(5), toArray); // [1,2,3,4,1]
