## Description
编写一个函数，将数组（第一个参数）拆分为size的长度（第二个参数），并将它们作为二维数组返回。如果卡住，请记得使用Read-Search-Ask 。编写自己的代码。
## Instructions
## Tests
```yml
tests:
- text: 'chunkArrayInGroups(["a", "b", "c", "d"], 2)应返回[["a", "b"], ["c", "d"]] 。'
testString: 'assert.deepEqual(chunkArrayInGroups(["a", "b", "c", "d"], 2), [["a", "b"], ["c", "d"]], "chunkArrayInGroups(["a", "b", "c", "d"], 2) should return [["a", "b"], ["c", "d"]].");'
- text: 'chunkArrayInGroups([0, 1, 2, 3, 4, 5], 3)应返回[[0, 1, 2], [3, 4, 5]] 。'
