我试图弄清楚如何迭代使用符号名称来唯一标识属性的对象。例如，如果我有这个对象：

   const bowl1 = {

   for (var fruit in bowl1) {
       var item = bowl1[fruit];
       console.log(`${fruit}: `, item);
   }

   OUTPUT:
   apple:  { color: 'red', weight: 136.078 }
   banana:  { color: 'yellow', weight: 183.151 }
   orange:  { color: 'orange', weight: 170.097 }
   peach:  { color: 'yellow', weight: 176.845 }
