将对象转换为数组

let obj = {
        test1: "aa",
        test2: "bb",
        test3: "cc",
        test4: "dd",
        test5: "ff",
        test6: "ee"
      };

转换为：

 let arr = [];
  for (let key in obj) {
    let newobj = {};
    newobj[key] = obj[key];
    arr.push(newobj);
  }

  console.log( arr);
