根据属性值创建新的对象数组

Question

我想根据接口值创建一个新的对象数组。 就像我们需要对具有相同接口值的对象进行分组。新数组就像两个具有相同接口值的新对象。因此，在新生成的对象数组中，将有两个对象。比如GE5和GE6。我有一个限制，只能使用ES5。

Answer 1

应该有循环逻辑

逻辑

• 循环遍历data 数组。哪个是输入。
• 循环遍历data的每个节点中的cloudServices节点，找到distict值。
• 遍历这些不同的值，并使用Array.filter 生成一组每个不同的值。
• 聚合数据数组中每个节点的所有剩余值，cloudServices 节点除外。
• 使用此剩余值和上述生成的组生成最终对象。

ES5 实现
