已知：

1. js文件中的data中有空数组 array[]

2. 最终的数组array的样式如下所示：

   array[

   {name1:value,describe:[{key1:value1,key2:value2,...,key3:value3},{key1:value1,key2:value2,...,key3:value3},...{key1:value1,key2:value2,...,key3:value3}]},

   {name2:value,describe:[{key1:value1,key2:value2,...,key3:value3},{key1:value1,key2:value2,...,key3:value3},...{key1:value1,key2:value2,...,key3:value3}]},

   ...

   {nameN:value,describe:[{key1:value1,key2:value2,...,key3:value3},{key1:value1,key2:value2,...,key3:value3},...{key1:value1,key2:value2,...,key3:value3}]}

   ]

3.数组1->对象1->数组2->对象2的结构，在数组2中添加对象2

• 希望提供的能力

1. 如何向array中添加describe:[];

2. 添加完describe:[]后如何添加各obeject,即{key1:value1,key2:value2,...,key3:value3}

3. 如何在数组2中添加对象2
