I am trying to manipulate an array of objects. It's a big tree as you u can see below.

I want to get both key value of `la` and `ld` at the zero index of the `products` array and put them beside `c` (in the `dop` array).

Please find my codepen link in comments not sure why I am unable to share code pen link here

```
const arr = [
  {
    a: 1,
    dop: [
      {
        c: 3,
        //la: 11,
        //ld: 33
        products: [
          { ld: 11, la: 33 }, // <--- zero index
          { ld: 233, la: 44 } // <--
        ]
      },

      { d: 4, e: 4 }
    ]
  },

  {
    a: 1,
    dop: [
      {
        c: 3,
        //la: 11,
        //ld: 33
        products: [
          { ld: 11, la: 33 },
          { ld: 233, la: 44 }
        ]
      },

      { d: 4, e: 4 }
    ]
  }
];

```
