How to parse duplicate data in a list of objects based on multiple keys having the same value, where one key has a value of an array of objects

As the title states, I am trying to store a list of duplicate objects based on specific key:value pairs being the same.

The goal is to parse the information and return a list of duplicate items. A duplicate item is when the ID , title, items are a match.
The main problem I’m having with this is that inside each object, one of the keys to compare is an array holding a list of objects as values.

How would you go about this problem, looping through an array of objects to determine if the items array are duplicate?

Below is just a small example of the JSON data.

Should return :
whole object of pk:”0002″ and pk”0003″ since they are duplicate. Should not return Object pk:”0001″ and pk “0004” since their array of items:[{}] are not equal.

My attempt can determine if the ID and titles are a match but I can’t get the items to match:

var data = [
{ pk: "0001", ID: "1A", title: "Material 15", items: [{ title: "Info", value: "" }, { title: "Type", value: "" }, { title: "EXTRA", value: "55" }, ], }, 
{ pk: "0002", ID: "1A", title: "Material 1", items: [{ title: "Info", value: "" }, { title: "Type", value: "" }, ], }, 
{ pk: "0003", ID: "1A", title: "Material 1", items: [{ title: "Info", value: "" }, { title: "Type", value: "" }, ], }, 
{ pk: "0004", ID: "1A", title: "Material 15", items: [{ title: "Info", value: "" }, { title: "Type", value: "" }, ], }, 
];


let duplicates = [];
data.forEach((el, i) => {
  data.forEach((element, index) => {
    if (i === index) return null;
    if (element.ID === el.ID && element.title === el.title) {
      if (!duplicates.includes(el)) {
        //Issue here -> I want to compare the array of items but im not sure how to ?
        //Attempt:
        // I think I understand that this is wrong due to the indexes not sure how you would find this ?

        // if (element.items[i] === el.items[i]) {
        //   duplicates.push(el);
        //   console.log("Test");
        // }

        duplicates.push(el);
      }
    }
  });
});
console.log("duplicates", duplicates);
