Benchmark: string array sort comparison 2

Script Preparation code:

var string1 = ["lorem", "ipsum", "sim", "dolor", "amet", "sensei", "shaolin", "eight", "nine", "ten"];
var string2 = ["lorem", "ipsum", "sim", "dolor", "amet", "sensei", "shaolin", "eight", "nine", "ten"];
for(let i=0; i<2; i++) string1.push(...string1);
for(let i=0; i<5; i++) string2.push(...string2);
var arr21 = string1;
var arr22 = string1;
var arr51 = string2;
var arr52 = string2;

Tests:

simple sort
arr21.sort()
localeCompare sort
arr22.sort((a,b) => a.localeCompare(b))

Let's dive into the explanation of what's being tested in the provided JSON.

**Benchmark Definition**

The benchmark is designed to compare two approaches for sorting an array of strings:

1. **Simple Sort**: This approach uses the built-in `sort()` method without any custom comparators or options.
2. **LocaleCompare Sort**: This approach uses the `sort()` method with a custom comparator function that compares strings using the locale's sorting rules.

**Comparison**

The two approaches are compared in terms of their performance, specifically the number of executions per second on a Mac OS X 10.15.7 desktop environment running Safari 15.

**Options Compared**

In the LocaleCompare Sort approach, an additional option is used: `localeCompare()`, which allows for locale-specific sorting rules to be applied when comparing strings.

**Pros and Cons**

* **Simple Sort**: Pros:
	+ Easy to use and understand
	+ Built-in implementation, so no extra dependencies are required
* Cons:
	+ May perform poorly on certain languages or characters (e.g., non-ASCII characters)
* **LocaleCompare Sort**: Pros:
	+ Provides locale-specific sorting rules for more accurate comparisons
	+ Can handle a wider range of characters and languages
* Cons:
	+ Requires additional dependencies (locale-specific sorting functions) and setup

**Library**

In the LocaleCompare Sort approach, the `String.prototype.localeCompare()` method is used. This method is part of the ECMAScript standard and provides locale-specific comparison functionality.

**Special JS Feature or Syntax**

There isn't any specific JavaScript feature or syntax being tested in this benchmark. The focus is on comparing two sorting approaches rather than exploring advanced features.

**Other Considerations**

When choosing between these approaches, consider the following:

* If you need to sort arrays of strings with locale-specific rules, use `localeCompare()` (LocaleCompare Sort).
* If you're working with simple sorting tasks and don't need locale-specific rules, use the built-in `sort()` method (Simple Sort).

**Alternatives**

If you want to explore other sorting approaches or testing scenarios, consider the following alternatives:

* Use the `Array.prototype.sort()` method with a custom comparator function for more control over the sorting process.
* Test other sorting algorithms like QuickSort, MergeSort, or HeapSort.
* Experiment with different data sets, such as arrays of numbers, dates, or objects, to see how they affect performance.

Keep in mind that MeasureThat.net is specifically designed to test JavaScript microbenchmarks, so you may want to explore other platforms for testing more general-purpose programming languages or scenarios.
