Benchmark: Passing objects with raw values vs passing just raw values vs array of values spread

Script Preparation code:

var a = "Here's a string value";
var b = 5; // and a number
var c = false;

var object = {
  a, b, c
}

var array = [
  a, b, c
];

var passObject = ({a,b,c}) => {
  return a.length + b * c ? 2 : 1;
}

var passRawValues = (val_a, val_b, val_c) => {
  return val_a.length + val_b * val_c ? 2 : 1;
}

var passArray = ([a,b,c]) => {
  return a.length + b * c ? 2 : 1;
}


var x = 0;

Tests:

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