I have a list which can have the following kinds of values:

[
  { "a": "ABC", "b": "DEF", "c": "IAABS", "d": "XYZ" },
  { "a": "ABC", "b": "DEF", "c": "*ALL", "d": "*ALL" },
  { "a": "LMN", "b": "BIFPSR", "c": "*ALL", "d": "FGH" },
  { "a": "YUI", "b": "BIFPSR", "c": "TEST", "d": "XYZ" },
  { "a": "LMN", "b": "BIFPSR", "c": "TEST", "d": "FGH" },
]

Below are my test cases which I want to pass:

Case 1: If more than 1 object conatins same libraryName & sourceFile as a combination then check if any of those objects contain memberName & memberType as *ALL or not. If yes, then remove the other objects.

Case 2: If more than 1 object conatins same libraryName & sourceFile as a combination then check if any of those objects have memberName as *ALL and memberType as any value. If yes, then based on the memberType‘s value check which objects have same value for the same libraryName & sourceFile as a combination then those objects need to be removed.

Case 3: If above cases don’t match/list is blank as it is it should output.

Expected Output from the above cases:

[
  { "a": "ABC", "b": "DEF", "c": "*ALL", "d": "*ALL" },
  { "a": "LMN", "b": "BIFPSR", "c": "*ALL", "d": "FGH" },
  { "a": "YUI", "b": "BIFPSR", "c": "TEST", "d": "XYZ" }
]

For the Case 1, I tried something like this below but it is printing the original array only –

function abc(arr) {
    const seen = new Set(); // Set to store unique combination
    return arr.reduce((acc, obj) => {
        const key = `${obj.a}-${obj.b}`;
        if (!seen.has(key)) {
            seen.add(key);
            acc.push(obj); // Adding unique elements or objects with *ALL
        } else if (obj.c === '*ALL') {
            acc.push(obj);
        }
        return acc;
    }, []);
}
