期望拼成下列樹形數(shù)據(jù)格式(用jq或是es6實(shí)現(xiàn))
對應(yīng)關(guān)系：父的grade=子的fatherid
data:[

{
      label: '一級 1',
      children: [{
        label: '二級 1-1',
        children: [{
          label: '三級 1-1-1'
        }]
      }]
    }, {
      label: '一級 2',
      children: [{
        label: '二級 2-1',
        children: [{
          label: '三級 2-1-1'
        }]
      }, {
        label: '二級 2-2',
        children: [{
          label: '三級 2-2-1'
