Remove Duplicate Array and Merge The Values

ZaIn KhAn

I've an array of objects. I want don't want to render duplicates array but I want it's items to be merged with it's same one which is render example shown below.

Original Array

array = [
  {
    name: 'Test',
    items: [
      {
        id: 1,
        product_name: "Kbana 1",
      },
      {
        id: 2,
        product_name: "Kbana 2",
      },
    ]
  },
  {
    name: 'Test 2',
    items: [
      {
        id: 3,
        product_name: "Kbana 3",
      },
      {
        id: 4,
        product_name: "Kbana 4",
      },
    ]
  },
  {
    name: 'Test 2',
    items: [
      {
        id: 5,
        product_name: "Kbana 5",
      },
      {
        id: 6,
        product_name: "Kbana 6",
      },
    ]
  },
]

Now I have two same array objects which index is 1 and 2. Now I wants to merge index 2 items values with index 1. Like example below

array = [
      {
        name: 'Test',
        items: [
          {
            id: 1,
            product_name: "Kbana 1",
          },
          {
            id: 2,
            product_name: "Kbana 2",
          },
        ]
      },
      {
        name: 'Test 2',
        items: [
          {
            id: 3,
            product_name: "Kbana 3",
          },
          {
            id: 4,
            product_name: "Kbana 4",
          },
          {
            id: 5,
            product_name: "Kbana 5",
          },
          {
            id: 6,
            product_name: "Kbana 6",
          },
        ]
      }
    ]

var arr = [
  {
    name: 'Test',
    items: [
      {
        id: 1,
        product_name: "Kbana 1",
      },
      {
        id: 2,
        product_name: "Kbana 2",
      },
    ]
  },
  {
    name: 'Test 2',
    items: [
      {
        id: 3,
        product_name: "Kbana 3",
      },
      {
        id: 4,
        product_name: "Kbana 4",
      },
    ]
  },
  {
    name: 'Test 2',
    items: [
      {
        id: 5,
        product_name: "Kbana 5",
      },
      {
        id: 6,
        product_name: "Kbana 6",
      },
    ]
  },
]

const newArr = [];

for(var i = 0;i<arr.length;i++)
{
    var name = arr[i].name;
    for(var j = 0;j<arr.length;j++)
    {
       if(i != j)
       {
          if(name === arr[j].name)
          {
              arr[i].items = [...arr[i].items, ...arr[j].items]
              arr[j].name = "remove";
          }
       }
    }
}

arr = arr.filter(data => data.name !== "remove");

console.log(arr);
