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

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);

Let's break down the provided JSON and explain what's being tested, compared, and other considerations.

**Benchmark Definition:**

The benchmark measures how fast JavaScript can perform arithmetic operations using different methods:

1. Passing new objects (`passObject` function)
2. Passing just raw values (without creating a new object) (`passRawValues` function)
3. Passing an array of values (`passArray` function)

These functions are used to manipulate and calculate the value of `x`, which is initialized as 0.

**Comparison:**

The benchmark compares the execution speed of these three approaches:

* `passObject`: Creating a new object with `a`, `b_func()`, and `c` properties, and then passing it to the function.
* `passRawValues`: Passing raw values (`a`, `b_func()`, and `c`) without creating an object.
* `passArray`: Passing an array containing the raw values.

**Pros and Cons:**

1. **passObject**: Pros:
	* Simulates real-world scenario where objects are passed to functions.
	* Can be beneficial for developers who need to work with objects in their code.
Cons:
	* May lead to slower execution due to object creation and property access.
2. **passRawValues**: Pros:
	* Faster execution, as it avoids object creation and property access.
Cons:
	* May not accurately represent real-world scenarios where objects are passed.
3. **passArray**: Pros:
	* Similar performance characteristics to `passRawValues`, but with an array instead of individual values.
Cons:
	* May not be representative of real-world use cases where arrays are used.

**Library and Purpose:**

The `b_func` function is a closure that uses the `Math.floor` method to generate a random number between 0 and 9. The purpose of this library is to provide a simple way to generate random numbers for testing purposes.

**Special JS Feature or Syntax:**

There are no special JavaScript features or syntax used in this benchmark. However, it's worth noting that the use of closures (e.g., `b_func`) and property access (e.g., `obj.a.length` or `arr[0].length`) is an essential part of modern JavaScript programming.

**Alternatives:**

To test similar benchmarks, other alternatives could include:

1. Passing primitive values only (`passPrimitiveValues` function).
2. Using `const` or `let` variables instead of `var`.
3. Comparing the performance of different bitwise operators (e.g., `>>`, `<<`, etc.).

These alternative benchmarks would allow for further exploration of different JavaScript optimization techniques and their impact on execution speed.

Keep in mind that these alternatives should be designed to simulate real-world scenarios, ensuring accurate comparisons and representative results.
