我有以下数据

const data = [{
    id: 1,
    children: [{
        name: "test1",
        id: 1231,
    } ,{
        name: "test4",
        id: 1232,
        children: []
    }],
    data: {
        title: "33",
    }
},
{
    id: 2,
    children: [{
        name: "test2",
        id: 1234,
    }, {
        name: "test3",
        id: 1235,
        children: [{
            name: "test2-3",
            id: 1234,
        }]
    }],
    data: {
        title: "22",
    }
}];

我的尝试:

递归提取

  const forEach =  (tree, func) => {
    for (let i = 0; i < list.length; i++) {
      func(list[i])
      list[i].children && list.splice(i + 1, 0, ...list[i].children)
    }
  };

let result = []
let func = (node)=>{
    //不知道条件怎么写
}
forEach(data, func)

我想要的结果，就是

[
 {
     fater:{
        id:"1",
        data:{title:"33"}
    },
    sons:[
    {
        name: "test1",
        id: 1231,
    },
    {
        name: "test4",
        id: 1232,
    }
    ]
 },
    ...以此类推
]

感谢您的帮助.
