哪位大佬帮忙瞅一下，后端返回的树状结构的数据没有 pid和id，（后端传来的children不确定多少级），如何给树结构数据增加 pid和id？

function addId(tree) {
let id = 0;
return setIdAndPid(tree, null);
function setIdAndPid(arr, pid = null) {
for (let i = 0, len = arr.length; i < len; i++) {
arr[i].pid = pid;
arr[i].id = id;
if (arr[i].children) {
setIdAndPid(arr[i].children, id, id++);
}
id++;
}
return arr;
}
}
const result = addId(tree);
console.log(result);不太理解为什么是前端去加这个东西，一般需求是后端返回扁平的结构根据pid,id转成树
