Language/Type: JavaScript parameter mystery reference semantics

Assume the following functions are defined: 

function main() {
    let a = 1;
    let b = 2;
    let c = -3;
    mystery(a, b, c);
    mystery(c, 4, a);
    mystery(a + b, b + c, c + a);
}

function mystery(c, a, b) {
    console.log(b + " + " + c + " = " + a);
}
What console output would result from calling main?
mystery(a, b, c);
mystery(c, 4, a);
mystery(a + b, b + c, c + a);
