Script Preparation code:

var a = "Here's a string value";
var b_func = ()=>Math.floor(Math.random() * 10);; // and a number
var c = false;

var object = {
  a, b: b_func(), c
}

var array = [
  a, b_func(), c
];

var passObject = (obj) => {
  return obj.a.length + obj.b * obj.c ? 2 : 1;
}

var passRawValues = (val_a, val_b, val_c) => {
  return val_a.length + val_b * val_c ? 2 : 1;
}

var passArray = (arr) => {
  return arr[0].length + arr[1] * arr[2] ? 2 : 1;
}


var x = 0;

Tests:

Pass object
x << 1; x ^= passObject({a,b:b_func(),c});
Pass raw values
x << 1; x ^= passRawValues(a, b_func(), c);
Pass array
x << 1; x ^= passArray(array);

Updated because it looks like Firefox optimizes away the entire test

Pass object

Pass raw values

Pass array
