数组对象转换为二维数组应该如何转换

Question

a: [
      {
        nodes: [
          {
            nodeId: "*"
          }
        ],
        startsAt: "2023-01-06 16:17:41",
        endsAt: "2023-01-06 16:17:41"
      },
      {
        nodes: [
          {
            clusterId: "1111",
            nodeId: "1"
          },
          {
            clusterId: "1111",
            nodeId: "2"
          }
        ],
        startsAt: "2023-01-06 16:17:41",
        endsAt: "2023-01-06 16:17:41"
      },
      {
        nodes: [
          {
            clusterId: "222",
            nodeId: "3"
          },
          {
            clusterId: "2222",
            nodeId: "5"
          }
        ],
        startsAt: "2023-01-06 16:17:41",
        endsAt: "2023-01-06 16:17:41"
      }
    ]

把a转换为b
是antd中的Cascader级联选择那种数据形式，nodeId为*时代表全部选中，做数据回填
b: [
      {
        nodes: [[*,clusterId,nodeId ]],
        timeCycle: [startsAt, endsAt],
      },
    ],

map函数：

const a = [  {    nodes: [      {        nodeId: "*"      }    ],
    startsAt: "2023-01-06 16:17:41",
    endsAt: "2023-01-06 16:17:41"
  },
  {
    nodes: [
      {
        clusterId: "1111",
        nodeId: "1"
      },
      {
        clusterId: "1111",
        nodeId: "2"
      }
    ],
    startsAt: "2023-01-06 16:17:41",
    endsAt: "2023-01-06 16:17:41"
  },
  {
    nodes: [
      {
        clusterId: "222",
        nodeId: "3"
      },
      {
        clusterId: "2222",
        nodeId: "5"
      }
    ],
    startsAt: "2023-01-06 16:17:41",
    endsAt: "2023-01-06 16:17:41"
  }
];

const b = a.map(item => {
  const nodes = item.nodes.map(node => {
    const { clusterId, nodeId } = node;
    return [nodeId === "*" ? "*" : clusterId, nodeId];
  });

  return {
    nodes,
    timeCycle: [item.startsAt, item.endsAt],
  };
});
