將一個大數組分割成幾個小數組

function sliceArr(array, size) {
                var result = [];
                for (var x = 0; x < Math.ceil(array.length / size); x++) {
                    var start = x * size;
                    var end = start + size;
                    result.push(array.slice(start, end));
                }
                return result;
            }
