```
const listChunk = (list, size = 1, cacheList = []) => {
const tmp = [...list]
if (size <= 0) { return cacheList }
while (tmp.length) {
cacheList.push(tmp.splice(0, size))
}
return cacheList
}
console.log(listChunk([1, 2, 3, 4, 5, 6, 7, 8, 9])) // [[1], [2], [3], [4], [5], [6], [7], [8], [9]]
console.log(listChunk([1, 2, 3, 4, 5, 6, 7, 8, 9], 3)) // [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
console.log(listChunk([1, 2, 3, 4, 5, 6, 7, 8, 9], 0)) // []
console.log(listChunk([1, 2, 3, 4, 5, 6, 7, 8, 9], -1)) // []
