js将一个数组分成多个数组
1 将数组array分成长度为subGroupLength的小数组并返回新数组
function group(array, subGroupLength) {
let index = 0;
let newArray = [];
while(index < array.length) {
newArray.push(array.slice(index, index += subGroupLength));
}
return newArray;
}

var Array = [1,2,3,4,5,6,7,8,9,10,11,12];;
var groupedArray = group(Array, 6);
//得到的groupedArray 数组为:
groupedArray[[1,2,3,4,5,6],[7,8,9,10,11,12]]
