--description--

请编写一个函数，该函数将一个数组（第一个参数）拆分成若干长度为 size（第二个参数）的子数组，并将它们作为二维数组返回。

--hints--

chunkArrayInGroups(["a", "b", "c", "d"], 2) 应返回 [["a", "b"], ["c", "d"]]。

assert.deepEqual(chunkArrayInGroups(['a', 'b', 'c', 'd'], 2), [
  ['a', 'b'],
  ['c', 'd']
]);

chunkArrayInGroups([0, 1, 2, 3, 4, 5], 3) 应返回 [[0, 1, 2], [3, 4, 5]]。

assert.deepEqual(chunkArrayInGroups([0, 1, 2, 3, 4, 5], 3), [
  [0, 1, 2],
  [3, 4, 5]

--seed--

--seed-contents--

function chunkArrayInGroups(arr, size) {
  return arr;
}

chunkArrayInGroups(["a", "b", "c", "d"], 2);

--solutions--

function chunkArrayInGroups(arr, size) {
  let out = [];

  for (let i = 0; i < arr.length; i += size) {
    out.push(arr.slice(i, i + size));
  }

  return out;
}
