js中如何对嵌套数组进行filter过滤

listData = [
  {
    name: 'zhangsan'
    data: [A,B,C]
  },
  {
    name: 'lisi'
    data: [D,E,F]
  }
]

const filterRepositoryList = () => {
  if (
    !slectedInfo.sigSelected &&
    !slectedInfo.repositiorySelected &&
    !slectedInfo.maintainerSelected
  ) {
    repoRenderList.value = repositioryList.value.slice(0, 99);
    getSigList(initialParams);
  } else {
    SigList.value = _.filter(allList.value, (item: any) => {
      return (
        (!slectedInfo.sigSelected ||
          item.sig_name === slectedInfo.sigSelected) &&
        (!slectedInfo.repositiorySelected ||
          item.repos.find((subItem: string) => {
            return subItem === slectedInfo.repositiorySelected;
          })) &&
        (!slectedInfo.maintainerSelected ||
          item.maintainers.find((subItem: string) => {
            return subItem === slectedInfo.maintainerSelected;
          }))
      );
    });
    paginationData.value.total = SigList.value.length;
  }
};

// 安装了lodash，所以用了lodash的筛选
SigList.value = _.filter(allList.value, (item: any) => { 
  return (
    (!slectedInfo.sigSelected ||
     item.sig_name === slectedInfo.sigSelected) &&
     // 双层筛选主要代码，在data数组中进行find
     (!slectedInfo.repositiorySelected ||
     item.repos.find((subItem: string) => {
       return subItem === slectedInfo.repositiorySelected;
     })) &&
     (!slectedInfo.maintainerSelected ||
     item.maintainers.find((subItem: string) => {
        return subItem === slectedInfo.maintainerSelected;
      }))
    );
});

    // 搜索框过滤
  function searchFilter(list, key, num, prevList) {
        for (let i = list.length - 1; i >= 0; i--) {
            let item = list[i]
            if (item.children && Array.isArray(item.children) && item.children.length > 0) {
                searchFilter(item.children, key, i, list);
            } else {
                if (item.title && !item.title.includes(key)) {
                  list.splice(i, 1)
                }
            }
        }
        if (Array.isArray(list) && list.length == 0) {
          if(prevList && num){
            prevList.splice(num, 1)
          }
        }
    }
//调用
searchFilter(list,key)
