SelectedItems with primaryKey field only

We usually store only ids/value field in the DB for dropdown items. While fetching the record, we have only list of selected ids/value i.e. [‘Singapore’, ‘India’] instead of array of objects.

It would be good to have this feature where developer don’t have to manipulate the data for to pre-populate the selectedItems

this.dropdownList = [
      { "id": 1, "name": "India" },
      { "id": 2, "name": "Singapore" },
      { "id": 3, "name": "Australia" },
      { "id": 4, "name": "Canada" },
      { "id": 5, "name": "South Korea" },
      { "id": 6, "name": "Brazil" }
    ];

// Should allow selected items to be only array of primarykey
//  this.selectedItems = [ 'India', 'Singapore', 'Australia']; 
     
this.selectedItems = [
      { "id": 1, "name": "India" },
      { "id": 2, "name": "Singapore" }];

this.settings = {
      text: "Select Countries",
      selectAllText: 'Select All',
      unSelectAllText: 'UnSelect All',
      primaryKey: 'name',
      labelKey: 'name',
    };

I’ll add that it’s not clear to me what the purpose of primaryKey is
