Benchmark: array object bench v0.1

Tests:

store
let vstore = []; vstore['address'] = false; vstore['email'] = false; vstore['city'] = false; vstore['state'] = false; vstore['zip'] = false; vstore['country'] = false; vstore['name'] = false; vstore['phone'] = false; for ( let i = 0; i < vstore.length; i++) { vstore[i] = true; console.log(vstore[i]); }
valStore
const valStore = [{address: false},{email: false},{city: false},{state: false},{zip: false},{country: false},{name: false},{phone: false}] for ( let i = 0; i < valStore.length; i++) { valStore[i] = true; console.log(valStore[i]); }

Let's break down the provided benchmark and explain what is being tested.

**What is being tested:**
The benchmark tests how to initialize and populate an array (or an object, in the case of `valStore`) with values and log them out. The test is checking various ways of doing it, as indicated by the "v0.1" version in the benchmark definition.

**Options compared:**

There are two main approaches being compared:

1. **Array literal**: In this approach, a new array is created using the square brackets `[]` and then populated with values.
2. **Object literal**: This approach uses an object literal `{}` to create an object and then populates it with properties.

**Pros and Cons of each approach:**

* **Array literal:**
	+ Pros:
		- Lightweight and compact representation of the array.
		- Fast creation and access.
	+ Cons:
		- May not be as intuitive for complex data structures or nested objects.
* **Object literal:**
	+ Pros:
		- More intuitive for complex data structures or nested objects.
		- Can provide better type safety and auto-completion in editors.
	+ Cons:
		- May have a slight performance overhead compared to array literals.

**Library used (if any):**

In this case, there is no explicit library mentioned. However, it's worth noting that JavaScript provides several built-in data structures, including arrays and objects, which are being tested here.

**Special JS feature or syntax:**
There are no special features or syntaxes being tested in this benchmark.

**Other alternatives:**

If you were to write a similar benchmark, you might also consider testing:

* Using `Array.from()` to create an array from an iterable.
* Using destructuring assignment to initialize variables.
* Using ES6 classes or other object-oriented programming approaches to create complex data structures.

It's worth noting that the specific approach being tested here (array literals) is a fundamental part of JavaScript and has been widely used for many years. However, as JavaScript continues to evolve, new approaches may become more common or performance-critical.
