I have an input array of objects :

 [{
        "title": "popo",
        "Id": "123",
        "name": "john"

    },
    {
        "title": "test",
        "Id": "123",
        "name": "word"

    },
    {
        "title": "lala",
        "Id": "222",
        "name": "ref"

    },
    {
        "title": "mood",
        "Id": "222",
        "name": "trap"

    }]

And I need an output array of objects like this:

 [{
        AppId: "123",
        Titles: {
           'popo' : 'name',
           'test' : 'word',
        }
  },
  {
        AppId: "222",
        Titles: {
           'lala' : 'ref',
           'mood' : 'trap',
        }
  }]

which is grouping the data by the Id and manipulating key names. I tried using lodash and Array/Object functions but I cant get the result I want. Any idea how to approach this?
