Benchmark: Array.sort() vs Math.min / Math.max 4 elements v2

HTML Preparation code:

const arr = [2,35,67,3];

Script Preparation code:

const arr = [2,35,67,3];

Tests:

Array.sort
const arr = [2,35,67,3]; const a = arr.sort(); const min = a[0]; const max = a[a.length - 1];
Math min and max
const arr = [2,35,67,3]; const min = Math.min(...arr); const max = Math.max(...arr);

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

**Benchmark Definition**

The benchmark defines two test cases:

1. **Array.sort()**: This test case measures the performance of the `sort()` method on an array.
2. **Math min and max**: This test case measures the performance of using `Math.min()` and `Math.max()` functions to find the minimum and maximum values in an array.

**Script Preparation Code**

Both test cases use the same script preparation code:
```javascript
const arr = [2, 35, 67, 3];
```
This code creates a sample array with four elements.

**Html Preparation Code**

The HTML preparation code is identical to the script preparation code:
```html
const arr = [2, 35, 67, 3];
```
This is likely used to provide an input for the benchmark.

**Test Cases**

There are two test cases:

1. **Array.sort()**: This test case creates a copy of the `arr` array and sorts it using the `sort()` method. It then extracts the first element (`min`) and the last element (`max`) from the sorted array.
2. **Math min and max**: This test case uses the spread operator (`...`) to pass all elements in the `arr` array to `Math.min()` and `Math.max()`. The results are stored in `min` and `max`, respectively.

**Library**

None of these test cases use a JavaScript library specifically. However, they do rely on the built-in `Array` methods (`sort()`) and the `Math` object (`min()`, `max()`).

**Special JS feature or syntax**

There is no special JavaScript feature or syntax used in these test cases.

**Pros and Cons of Approaches**

1. **Array.sort()**:
	* Pros: Simple, intuitive, and widely supported.
	* Cons: Can be slow for large datasets due to the overhead of sorting.
2. **Math min and max**:
	* Pros: Fast and efficient, as it only requires a single pass through the array.
	* Cons: May not work correctly if the array is sorted in reverse order or has duplicate elements.

**Other Considerations**

When choosing between these two approaches, consider the following:

* If you need to sort an array frequently, `Array.sort()` might be a better choice. However, this comes at the cost of performance.
* If you only need to find the minimum and maximum values in an array, using `Math.min()` and `Math.max()` is likely faster.

**Alternatives**

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

1. Using a priority queue or heap data structure.
2. Sorting the entire array and then extracting the first and last elements.
3. Using a custom algorithm that takes advantage of the specific characteristics of your data.

In the context of MeasureThat.net, these alternatives would likely be implemented using JavaScript code and measured for performance.
