{
  "ccInput": [
    {
      "designSummaryId": 6,
      "CCType": "A",
      "CCTypologyCode": "A",
      "Amount": "1"
    },
    {
      "designSummaryId": 7,

I don't know much about TypeScript, but I do know you can set the array to []. However, for those of you looking to get rid of only part of an array but not all of it, the simplest way to do so that I know of is to just set each value to 0 for numbers, '' for characters, "" for Strings, etc.

If you want to remove some objects from your array, use Array.prototytpe.filter().

You can do it in an immutable way by copying each property of your object using the spread operator and then filter the ccInput property:

const obj = {ccInput:[{designSummaryId:6,CCType:"A",CCTypologyCode:"A",Amount:"1"},{designSummaryId:7,CCType:"",CCTypologyCode:"",Amount:""}]};

const result = { ...obj, ccInput: obj.ccInput.filter(x => x.CCType && x.CCTypologyCode) };

console.log(result);

Or if you want to modify your object in place, simply reassign the ccInput property:

const obj = {ccInput:[{designSummaryId:6,CCType:"A",CCTypologyCode:"A",Amount:"1"},{designSummaryId:7,CCType:"",CCTypologyCode:"",Amount:""}]};

obj.ccInput = obj.ccInput.filter(x => x.CCType && x.CCTypologyCode);

console.log(obj);
