合并两个具有多个匹配项的Javascript对象

Question

我想要合并两个对象。我几乎成功地回答了这个问题的答案（Merge two unordered objects with different keys but same value?）。

问题在于，在我的“transpatterns”对象中，我有两个匹配“Intercom”键的模式。但是，在我的输出中，它只需要第二个。我需要它在同一个键下列出。

这是我的代码：

var hash = {};

var partitions = [{
        '$': {
            uuid: '{0F314A21-B066-B597-BCFA-6EC88CF8813B}'
        },
        name: ['AllPhones']
    },
    {
        '$': {
            uuid: '{4DCF3A89-ADA1-2770-4154-F6E0204D9A71}'
        },
        name: ['Unity_Connection']
    },
    {
        '$': {
            uuid: '{B653BC00-2D90-790C-AE0D-16C3DD2F8EDD}'
        },

    },
    {

我能够解决我的问题。在确定合并两个对象之前，我确定需要使用与同一个键关联的多个项目来折叠对象。我能够使用这个问题的答案来帮助我做到这一点。 How to combine JSON object with same key and add their other corresponding values?

这是我提出的代码似乎很好用。
