js循环取出两个属性组成新的属性名称数组

原来的格式：

dataObj: [
        {
          id: 1,
          pattern: "白天模式",
          upTime: "08:00",
          downTime: "18:00",
          notificationMethod: 1,
          modelUrgency: ["1", "2", "3", "4"],
         
        },
        {
          id: 2,
          pattern: "夜间模式",
          upTime: "18:01",
          downTime: "07:59",
          notificationMethod: 2,
          modelUrgency: ["3", "4"],
        
        },
      ],

想要把 upTime和downTime 取出来 ，放到newTime数组中

 实现方法

//for 循环 .data 是原数组 dataObj

 for (let i = 0; i < data.length; i++) {
　　 data[i].time = []; 
　　 data[i].newtime.push(data[i].upTime, data[i].downTime);
 } 
console.log(data)
