Language/Type: JavaScript parameter mystery reference semantics

Assume the following functions are defined: 

function main() {
    let bit = "byte";
    let byte = bit;
    let nibble = "bit";
    mystery(bit, nibble, "nibble");
    mystery("byte " + bit, byte + " bit", "nibble nibble");
    mystery(bit, bit, nibble + " " + bit);
}

function mystery(nibble, bit, byte) {
    byte = "nibble";
    console.log("How many " + bit + "s in a " + byte + " of " + nibble + "s?");
}

What console output would result from calling main?

mystery(bit, nibble, "nibble");
mystery("byte " + bit, byte + " bit", "nibble nibble");
mystery(bit, bit, nibble + " " + bit);
