why is my data not sorting javascript sort function

Question

I tried making a function called sort and no matter what it won't sort.

I'm sorting an array of javascript objects and using the paramater name that's inputted as the sort criteria, for sorting a table of different values

const sort = (data, ascending, param) => {
    console.log(data, ascending, param);
    let a2 = data.sort((a, b) =>
        ascending ? a[param] - b[param] : b[param] - a[param]
    );
    console.log(a2);
};

console output before and after the sort seems to be the same

[
    {
        "id": 1,
        "first_name": "ralph",
        "last_name": "nader",
        "age": 102,
        "phone": 1234
    },
    {
        "id": 2,
        "first_name": "Turkey",
        "last_name": "Face",
        "age": 43,
        "phone": 4444
    },
    {
        "id": 3,
        "first_name": "Taco",
        "last_name": "Breath",
        "age": 43,
        "phone": 4444
    },
    {
        "id": 4,
        "first_name": "fish",
        "last_name": "Butt",
        "age": 43,
        "phone": 4444
    }
]

[
    {
        "id": 1,
        "first_name": "ralph",
        "last_name": "nader",
        "age": 102,
        "phone": 1234
    },
    {
        "id": 2,
        "first_name": "Turkey",
        "last_name": "Face",
        "age": 43,
        "phone": 4444
    },
    {
        "id": 3,
        "first_name": "Taco",
        "last_name": "Breath",
        "age": 43,
        "phone": 4444
    },
    {
        "id": 4,
        "first_name": "fish",
        "last_name": "Butt",
        "age": 43,
        "phone": 4444
    }
]

here's the html (jsx)

<Col2 onClick={() => sort(users, false, 'first_name')}>First Name</Col2>
