JS基石之-----数组转换为树结构函数

我们常常在做后台管理系统的时候 需要对数据进行组装成一个树装结构，这里特地将此方法进行封装：

let data = [
    { id: , text: 't11', parentId:  },
    { id: , text: 't11', parentId:  },
    { id: , text: 't11', parentId:  },
    { id: , text: 't11', parentId:  },
    { id: , text: 't11', parentId:  },
    { id: , text: 't11', parentId:  }
]
function treeData (data, id, parentId, childName) {
    let cloneData = JSON.parse(JSON.stringify(data))
    return cloneData.filter((father) => {
        let newArr = cloneData.filter((child) => {
            return father[id] === child[parentId]
        })
        father[childName] = newArr
        return father[parentId] ===
    })
}
let msg = treeData(data, 'id', 'parentId', 'childaaa')
console.log(msg)
