Get unique values corresponding to the keys from an array of objects in JavaScript

My array looks like this

const arr1 = [
  {
    "Param1": "20",
    "Param2": "8",
    "Param3": "11",
    "Param4": "4",
    "Param5": "18",
    "Param6": "20",
    "Param7": "8"
  },
  {
    "Param6": "21",
    "Param7": "8",
    "Param8": "11",
    "Param9": "4",
    "Param10": "18"
  },
  {
    "Param1": "20",
    "Param2": "8",
    "Param3": "10"
  }
]

I wanted to remove the duplicate key value pairs existing in the objects.
Expected result:

arr1 = [
  {
    "Param1": "20",
    "Param2": "8",
    "Param3": "11",
    "Param4": "4",
    "Param5": "18",
    "Param6": "20",
    "Param7": "8"
  },
  {
    "Param6": "21",
    "Param8": "11",
    "Param9": "4",
    "Param10": "18"
  },
  {
    "Param3": "10"
  }
]

The desired output is an array containing objects having unique key value pairs. How can I get such an array?

Algorithm:

• Create a map seen in the format of {param: {value: boolean}} which will indicate whether the param with this value was already seen
• Create a result array that will store the unique params
• Traverse through the input array, get the keys of the current element, and traverse through them.
• Check if the param with this value was already seen, if yes, ignore it; otherwise add it to the result and mark it as seen
• Return the result array.

Implementation:

const removeDuplicates = (arr: Record<string, string>[]) => {
    return arr.reduce<{
        seen: Record<string, Record<string, boolean>>;
        result: Record<string, string>[];
    }>(
        (acc, item) => {
            acc.result.push(
                Object.fromEntries(
                    Object.entries(item).filter(([key, value]) => {
                        acc.seen[key] = acc.seen[key] ?? {};
                        if (acc.seen[key][value]) return false;
                        acc.seen[key][value] = true;

                        return true;
                    }),
                ),
            );
            return acc;
        },
        { seen: {}, result: [] },
    ).result;
};
