Benchmark: Intl.Collator vs Sort

Script Preparation code:

var collator = new Intl.Collator(undefined, {numeric: true, sensitivity: 'base'});
var arr = ['201','2','203','25','27','219','112','2ed', '21edd', '22eddie','apple', 'cat']
var x = arr.sort(collator.compare)
var y = arr.sort()

Tests:

Intl.Collator
console.log(x)
Sort
console.log(y)

Let's break down the provided benchmark and its test cases.

**Benchmark Overview**

The benchmark compares two approaches for sorting strings: using the `Intl.Collator` API (also known as the internationalization API) and the built-in `sort()` method of arrays in JavaScript. The goal is to determine which approach is faster.

**Options Compared**

There are two options being compared:

1. **Intl.Collator**: This option uses the `Intl.Collator` API, which provides a way to compare strings based on cultural rules and preferences.
2. **Sort**: This option uses the built-in `sort()` method of arrays in JavaScript, which sorts elements in ascending order.

**Pros and Cons**

Here's a brief overview of each approach:

* **Intl.Collator**:
	+ Pros: Can handle complex sorting tasks, provides cultural awareness, and can be customized.
	+ Cons: May have higher overhead due to its complexity, and might not be as efficient as the built-in `sort()` method for simple cases.
* **Sort**: 
	+ Pros: Typically faster than Intl.Collator, especially for simple cases, and is a widely supported feature in most JavaScript engines.
	+ Cons: Does not provide cultural awareness or customization options.

**Library Usage**

In this benchmark, the `Intl.Collator` library is used to create an instance that compares strings based on cultural rules. The `compare()` method of the collator object is then called with the array elements as arguments to sort them.

**Special JavaScript Feature/Syntax**

There is no special JavaScript feature or syntax being tested in this benchmark, apart from the use of the Intl.Collator API and the built-in sort() method.

**Other Alternatives**

If you were looking for alternative sorting methods in JavaScript, some other options include:

* Using a custom comparison function with the `sort()` method
* Using the `Array.prototype.every()` method or `Array.prototype.some()` method to filter out certain elements before sorting
* Using a third-party library like Lodash's `sortBy()` function

Overall, this benchmark provides a useful comparison between two approaches to string sorting in JavaScript, and can be helpful for developers who need to optimize their code for performance.
