Benchmark: ISO 8601 vs Epoch

Script Preparation code:

const arr = []

Tests:

ISO 8601
const arr = [] for (var i = 0; i < 50000 ; i++) { arr.push(new Date("2019-09-26T07:58:30.996+0200").valueOf()) }
Epoch
const arr = [] for (var i = 0; i < 50000 ; i++) { arr.push(1569455880000) }

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

**What is being tested?**

The test cases compare two approaches to generate dates in JavaScript:

1. **ISO 8601**: This method uses the International Organization for Standardization (ISO) 8601 date format, which is a standardized way of representing dates and times using letters (A-Z) and digits (0-9). In this case, the test generates an array of dates with the specific value "2019-09-26T07:58:30.996+0200".
2. **Epoch**: This method uses Unix time, also known as the Epoch, which is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. In this case, the test generates an array of dates with a fixed value representing the same date in Unix time (1569455880000).

**Options being compared**

The two options are compared in terms of performance, specifically the number of executions per second.

**Pros and cons of each approach:**

* **ISO 8601**:
	+ Pros:
		- More human-readable format
		- Less prone to errors due to the standardized format
	+ Cons:
		- May be slower than Epoch due to the string manipulation required for formatting
* **Epoch**:
	+ Pros:
		- Faster execution due to the direct numerical representation of time
	+ Cons:
		- Less human-readable format, may require additional processing to display dates in a readable format

**Library usage**

In the provided benchmark, there is no explicit library usage mentioned. However, it's worth noting that the `Date` object and its methods are used extensively in both test cases.

**Special JavaScript features or syntax**

There doesn't appear to be any special JavaScript features or syntax being tested or utilized in this benchmark.

**Other alternatives**

If you wanted to compare these approaches with alternative methods, some options could include:

* Using a Date library like Moment.js to generate dates
* Comparing the performance of different date formats (e.g., ISO 8601 vs. RFC 2822)
* Testing the performance of different programming languages or implementations that handle dates differently

Keep in mind that these alternatives would likely require significant changes to the benchmark setup and test cases.

Let me know if you'd like me to elaborate on any of these points!
