Benchmark: Sorting functions Array.sort vs Math.min+Math.max

Script Preparation code:

var v1 = 12345678;
var v2 = 23456789;

var arr = [v2, v1]

Tests:

Array.sort
var minFn = (a, z) => a - z; var maxFn = (a, z) => z - a; var min = arr.sort(minFn)[0]; var max = arr.sort(maxFn)[0];
Math min and max
var min = Math.min(...[v2, v1]); var max = Math.max(...[v2, v1]);

Let's break down the benchmark definition and test cases to understand what is being tested.

**Benchmark Definition**

The benchmark definition represents two different approaches to find the minimum and maximum values in an array:

1. Using the `Array.sort()` method with a custom comparison function (`minFn` and `maxFn`).
2. Using the `Math.min()` and `Math.max()` functions directly on the array elements.

**Options Compared**

The two options being compared are:

* **Option 1:** Using `Array.sort()` with custom comparison functions.
	+ Pros:
		- Allows for more control over the sorting algorithm and can be optimized for specific use cases.
		- Can handle complex data structures, such as objects or arrays of different lengths.
	+ Cons:
		- Sorts the entire array, which may not be necessary if only the minimum or maximum value is needed.
		- May have a higher overhead compared to using `Math.min()` and `Math.max()`.
* **Option 2:** Using `Math.min()` and `Math.max()` functions directly on the array elements.
	+ Pros:
		- Faster execution time since it only needs to iterate over the minimum or maximum values in the array.
		- More lightweight compared to using `Array.sort()`.
	+ Cons:
		- Limited control over the sorting algorithm and may not be suitable for complex data structures.

**Library Used**

There is no library explicitly mentioned in the benchmark definition. However, it's worth noting that the `Array.sort()` method uses the built-in sort algorithm implemented by the browser or JavaScript engine.

**Special JS Features/Syntax**

This benchmark does not use any special JavaScript features or syntax beyond what is standard in modern JavaScript (ES6+).

**Other Considerations**

When deciding between these two options, consider the following:

* If you need to find both the minimum and maximum values in an array and want more control over the sorting algorithm, `Array.sort()` might be a better choice.
* If you only need to find one of the extreme values (min or max) and want the fastest execution time, using `Math.min()` and `Math.max()` might be more suitable.

**Alternatives**

Other alternatives for finding minimum and maximum values in an array include:

* Using the `reduce()` method with a custom callback function.
* Using a library like Lodash's `minBy()` and `maxBy()` functions.
* Implementing a custom sorting algorithm using a data structure like a heap or a priority queue.

However, these alternatives might not be as straightforward to implement or optimize as the two options being compared in this benchmark.
