Answer 1

您可以使用 array.reduce()按 server 和 Spread 分组获取 other 对象字段的语法:

let data = [   {
          "id": 19,
          "server": "Data1",
          "dl": "35.88 Mbit/s",
          "ul": "46.76 Mbit/s",
        },
        {
          "id": 30,
          "server": "Data1",
          "dl": "45.06 Mbit/s",
          "ul": "48.25 Mbit/s",
        },
        {
          "id": 26,
          "server": "Data1",
          "dl": "47.96 Mbit/s",
          "ul": "47.89 Mbit/s",
        } ]
        
 let result = data.reduce((state,current) => {
     let {server, ...others} = current;
     if(state[server]){
         state[server].push(others);
     } else {
         state[server] = [others];
     }
     return state;
 }, {});
 
 console.log(result);
