请问js如何每隔两个逗号将字符串分割成一个数组

Question

008,00801,008,00802,009,00901
像这样的数据每隔两个逗号分割成一个数组

Answer 1

function splitNumberByGroup(str, group) {
  var nums = str.split(',');
    return nums.reduce((res, num, i) => {
        res[i/group|0].push(num)
        return res;
    }, Array.from({length: Math.ceil(nums.length/group)}, () => []))
}

splitNumberByGroup('008,00801,008,00802,009,00901', 2)
