Guys thank you so much for your help. I have found solution to this issue, following is what I wanted.

this is my array with initial values set.

var arr = [
    {id: "", name: "", quantity: 0},
    {id: "", name: "", quantity: 0},
    {id: "", name: "", quantity: 0},
    {id: "", name: "", quantity: 0}
];

and I I can remove any object like this:

arr.splice(arr[index], 1);

The solution is that filter your arr Array which has non-empty values like this-:

 var arr = [
    {id: "", name: "", quantity: 0},
    {id: "", name: "", quantity: 0},
    {id: "", name: "", quantity: 0},
    {id: "", name: "", quantity: 0}
];

 arr = arr.filter((obj)=>obj.id!==''); // you can use any field to filter 
 arr = arr.filter((obj)=>obj.id!=='' || obj.name!=='');// multiple fields to filter

Now your arr variable will be updated with new array of objects with non-empty fields

at the beginning you must know which object you want to delete it (for example the object whose id = x)

then you can use this code

arr = arr.filter(function(e){ return e.id != x });

You can use splice method, It accepts the index(start) of the to be removed element and also the deleteCount that is number of elements to be removed from the starting index

var arr = [{
    id: "1",
    name: "A",
    quantity: 1
  },
  {
    id: "2",
    name: "B",
    quantity: 2
  },
  {
    id: "3",
    name: "C",
    quantity: 3
  },
  {
    id: "4",
    name: "D",
    quantity: 4
  }
];
arr.splice(1, 1)
console.log(arr)
