使用Map將資料變成自己想要的

最近有一些大的資料是需要我們前端來寫死的，後臺就只給了我們散亂的資料，至於要變成ui控制元件想要的那種資料格式，得用js改造一番，我使用了es6的Map方法來改造資料
如我要處理的資料如下：

--AgentMetrics
agent.alive

--CpuMetrics

cpddsa
cpsfaf

我需要改造成一種樹的解構，像下面這樣

{
        title: 'parent 1',
        key: '0-0',
        children: [
          {
            title: 'parent 1-0',
            key: '0-0-0',
            children: [
              {
                title: 'leaf',
                key: '0-0-0-0',
              },
              {
                title: 'leaf',
                key: '0-0-0-1',
              },
            ],
          },
          {
            title: 'parent 1-1',
            key: '0-0-1',
            children: [
              {
                title: (
                  <span
                    style={{
                      color: '#1890ff',
                    }}
                  >
                    sss
                  </span>
                ),
                key: '0-0-1-0',
              },
            ],
          },
        ],
      }
