js 递归取出想要的数据。

[自先沉稳UP]

        var obj = [
            {
                "id": 1,
                "name": "大天使1",
                "children": [{
                        "id": 2,
                        "name": "大天使2",
                        "children": [{
                                "id": 3,
                                "name": "大天使3",
                                "children": [{
                                    "id": 4,
                                    "name": "大天使4",
                                    "children": []
                                }]
                        }]
                    }]
            },
            {
                "id": 5,
                "name": "大天使5",
                "children": []
            },
            {
                "id": 6,
                "name": "大天使6",
                "children": []
            }
        ]

需求是这样的， 假如上边是后台返回的数据，我要把数据变成一层， 也就是想要这样：

var obj = [
            {"id": 1, "name": "大天使1"},
            {"id": 2, "name": "大天使2"},
            {"id": 3, "name": "大天使3"},
            {"id": 4, "name": "大天使4"},
            {"id": 5, "name": "大天使5"},
            {"id": 6, "name": "大天使6"}
        ]

请问要如何递归处理？

[无聊的星期天]

recursion = function (data, children = 'children', arr = []) {
for (let i = 0; i < data.length; i++) {
arr.push({ id: data[i].id, name: data[i].name })
if (data[i][children] && data[i][children].length) {
recursion(data[i][children], (children = 'children'), arr)
}
}
return arr
}
