需求是找到对应code第一次出现的位置，一下函数始终不能正确执行，大家帮忙改正下

let menus = [{
      code: 2,
      name: '222',
      children: [
        {
          code: 33,
          name: '222sa',
          children: [
            {
              code: 44,
              name: '22'
            }
          ]
        }
      ]
    },{
      code: 922,
      name: '922',
      children: [
        {
          code: 9222,
          name: '92222222dsadsa',
          children: [
            {
              code: 44222,
              name: '442222dsads'
            }
          ]
        }
      ]
    }]

    function digui(arr, code) {
      for(var i=0;i<arr.length;i++) {
        if(arr[i].code == code) {
          return arr[i]
        } else {
          if (arr[i].children) {
            digui(arr[i].children, code)
          }
        }
      }
    }

    console.log(digui(menus, 44222))
