        "children": [

                ]

递归数据过滤（例如过滤最底层掉符合某个条件的数据）
```html
const filterMember = (key, data) => {
    const filterList = [];
    data.forEach((ele) => {
        const { member, ...other } = ele;
        if (member && member.length) {
            const currentEle = {
                member: [],
                ...other
            };
            const result = filterMember(key, member);

            if (result.length) {
                currentEle.member = result;
                filterList.push(currentEle);
            }
        } else if (other.age > key) {
            filterList.push(other);
        }
    });
    return filterList;
}
