前端将列表数据转树型数据

场景：后端返回列表数据，由前端根据业务需求完成树型数据转换，
常用于侧边导航菜单，下拉树型数据项等

export function listToTree(data: []) {var map: any = {},tree: any = []data.forEach((item: any) => {delete item?.childrendelete item?.paramsif (!item.label) {item.label = item?.name ?? item?.title}if (!item.value) {item.value = item?.id}map[item?.id] = item})/*** 以原数据量循环拼装父，子级*/data.forEach((item: any) => {var parent = map[item?.pid]if (parent) {(parent.children || (parent.children = [])).push(item)} else {tree.push(item)}})return tree
}

如：菜单
