Sum key values in array of objects where a key is the same

I have been playing with this a bit and I achieved a working function with one value, however I am trying to achieve summing multiple keys where a particular key is the same.

For example this is my data:

let data = [
    {
        name: 'John',
        value1: 1,
        value2: 2,
        value3: 3,
    },
    {
        name: 'Susan',
        value1: 1,
        value2: 2,
        value3: 3,
    },
    {
        name: 'John',
        value1: 1,
        value2: 2,
        value3: 3,
    },
    {
        name: 'Kate',
        value1: 1,
        value2: 2,
        value3: 3,
    },
    {
        name: 'Susan',
        value1: 1,
        value2: 2,
        value3: 3,
    },
];

And this would be the data after it has been processed:

data = [
    {
        name: 'John',
        value1: 2,
        value2: 4,
        value3: 6,
    },
    {
        name: 'Susan',
        value1: 2,
        value2: 4,
        value3: 6,
    },
    {
        name: 'Kate',
        value1: 1,
        value2: 2,
        value3: 3,
    },
]

The function I have for a single value is:

function sumValuesInArrayOfObjectsByKey(arr, key, value) {
    const map = new Map();
    for (const obj of arr) {
        const currSum = map.get(obj[key]) || 0;
        map.set(obj[key], currSum + obj[value]);
    }
    const res = Array.from(map, ([k, v]) => ({ [key]: k, [value]: v }));
    return res;
}

Any help or direction would be highly appreciated.

>Solution :

Don’t try to specify just a single key whose value you want to add up – iterate over all keys on the object other than name and add them to the matching value in the Map.

let data=[{name:"John",value1:1,value2:2,value3:3},{name:"Susan",value1:1,value2:2,value3:3},{name:"John",value1:1,value2:2,value3:3},{name:"Kate",value1:1,value2:2,value3:3},{name:"Susan",value1:1,value2:2,value3:3}];

function sumValuesInArrayOfObjectsByKey(arr, joiningKey) {
    const map = new Map();
    for (const { [joiningKey]: name, ...rest } of arr) {
        if (!map.has(name)) {
            map.set(name, { ...rest, [joiningKey]: name });
        } else {
            const mapObj = map.get(name);
            for (const [key, value] of Object.entries(rest)) {
                mapObj[key] = (mapObj[key] ?? 0) + value;
            }
        }
    }
    return [...map.values()];
}
console.log(sumValuesInArrayOfObjectsByKey(data, 'name'));
