chunk() function

요소들을 size 길이의 그룹으로 나눈 Iterable/AsyncIterable을 반환합니다. iterableIterator가 균등하게 나눠지지 않으면, 마지막 chunk는 나머지 요소들이 됩니다.

Signature:

declare function chunk<T>(
  size: number,
  iterable: Iterable<T>,
): IterableIterator<T[]>;

Example

const iter = chunk(2, [1, 2, 3, 4]);
iter.next(); // {done:false, value:[1, 2]}
iter.next(); // {done:false, value:[3, 4]}
iter.next(); // {done:true, value: undefined}

// with pipe
pipe([1, 2, 3, 4], chunk(2), toArray); // [[1, 2],[3, 4]]

await pipe(Promise.resolve([1, 2, 3, 4]), chunk(2), toArray); // [[1, 2],[3, 4]]

// with toAsync
await pipe(
  [
    Promise.resolve(1),
    Promise.resolve(2),
    Promise.resolve(3),
    Promise.resolve(4),
  ],
  toAsync,
  chunk(2),
  toArray,
); // [[1, 2],[3, 4]]
