JS——将一维数组拆分为指定长度二维数组

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;
}

 2,例如：

 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]]
