javascript - 合并每个键有多个匹配项的两个 Javascript 对象

Question

我有两个对象正在尝试合并。我几乎成功地回答了这个问题( Merge two unordered objects with different keys but same value? )。

问题是在我的“transpatterns”对象中，我有两个与“Intercom”键匹配的模式。然而，在我的输出中，只需要第二个。我需要它在同一个键下列出两者。

这是我的代码:

var hash = {};

var partitions = [{
        '$': {
            uuid: '{0F314A21-B066-B597-BCFA-6EC88CF8813B}'

    },
    {
        '$': {

我能够解决我的问题。我确定在合并两个对象之前需要折叠具有与同一键关联的多个项目的对象。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?

这是我想出的代码，看起来效果很好。
