Script Preparation code:

var data = {
    a: 1,
    b: 2,
    c: 3,
    d: 4,
    e: 5,
    f: 6,
    g: 7
}

function f1(a, b, c, d, e, f, g) {
    return a + b + c + d + e + f + g;
}

function f2({
    a,

    c,
    d,
    e,
    f,
    g
}) {
    return a + b + c + d + e + f + g;
}

Tests:

Multiple parameters
f1(data.a, data.b, data.c, data.d, data.e, data.f, Math.random())
Existing parameter object
data.g = Math.random(); f2(data)
Parameter object with spreading
f2({ ...data, g: Math.random() })
New parameter object
f2({ a: 1, b: 2, c: 3, d: 4, e: 5, f: 6, g: Math.random() })
