Benchmark: Passing 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 = 5; // and a number
var c = false;

var object = {
  a, b, c
}

var array = [
  a, b, 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;
}

Tests:

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

Let's dive into the benchmark and explore what's being tested.

**Benchmark Definition**

The provided JSON represents a JavaScript microbenchmark test case. The purpose of this test is to compare the performance of three different approaches for evaluating an object or array in a mathematical expression.

**Approaches Compared**

1. **Passing objects**: This approach passes a plain JavaScript object (`object`) as an argument to the `passObject` function.
2. **Passing just raw values**: In this case, each value is passed separately as arguments to the `passRawValues` function (e.g., `a`, `b`, and `c`). The function returns the result of evaluating a mathematical expression using these values.
3. **Passing array**: This approach passes an array (`array`) as an argument to the `passArray` function.

**Pros and Cons**

* **Passing objects**: Pros: Easier to understand and maintain, especially for developers familiar with object-oriented programming. Cons: May incur additional overhead due to object creation and evaluation.
* **Passing just raw values**: Pros: Can be faster since it avoids the overhead of object creation and passing. Cons: Requires careful handling of value types and potential issues with primitive type coercion.
* **Passing array**: Pros: Often leads to more efficient execution, as arrays can be optimized by JavaScript engines. Cons: May require additional setup or handling for developers unfamiliar with array-based solutions.

**Libraries and Special JS Features**

There are no libraries used in this benchmark, but it's worth noting that the `passRawValues` function uses primitive type coercion (e.g., `val_a.length + val_b * val_c`) which might not be explicitly handled by JavaScript engines. However, most modern browsers should handle such cases correctly.

**Other Considerations**

* The test case is designed to evaluate a simple mathematical expression using each approach.
* The choice of function names (`passObject`, `passRawValues`, and `passArray`) suggests that the primary focus is on evaluating expressions rather than performing complex computations.
* The benchmark results are provided for Safari 16 running on a Mac, which might not be representative of other browsers or platforms.

**Alternatives**

If you were to reimplement this benchmark with different approaches, some alternatives could include:

1. Passing objects with properties: Instead of passing individual values, pass an object with multiple properties and evaluate expressions using dot notation (e.g., `obj.a.length + obj.b * obj.c`).
2. Using functions or methods: Evaluate the expression within a function or method, which might provide additional context for developers.
3. Comparing with other data structures: Compare performance with different data structures, such as arrays or Maps, to see how each performs in various scenarios.

Keep in mind that these alternatives would require significant changes to the benchmark and may not provide direct comparisons with the original test case.
