Benchmark: foreach vs sort to find min max

Tests:

sort
const a = 1 const b = 2 const result = [a, b].sort((a, b) => a - b)
foreach
const arr = [1, 2] let min = arr[0]; let max = arr[0]; arr.forEach((n) => { if (n > max) { max = n; } else if (n < min) { min = n; } });

Let's break down the provided benchmark and its test cases to understand what is being tested, compared, and the pros/cons of different approaches.

**Benchmark Overview**

The benchmark measures the performance difference between two approaches: using `Array.prototype.sort()` (sort) and iterating over an array with a custom loop (foreach).

**Options Compared**

Two main options are compared:

1. **Sort**: Using the built-in `Array.prototype.sort()` method to sort the array.
2. **Foreach**: Iterating over the array manually using a custom loop.

**Pros/Cons of Different Approaches**

### Sort

Pros:

* Easy to implement and understand
* Built-in function, so no additional dependencies needed
* Fast and efficient when the array is already sorted or has a small number of elements

Cons:

* Requires sorting the entire array, which can be time-consuming for large arrays
* May not perform well if the array needs to be sorted multiple times

### Foreach

Pros:

* Can skip unnecessary work by iterating only over the relevant elements
* Can update variables (min and max) while iterating

Cons:

* More complex implementation compared to sort
* Requires manual loop, which can lead to errors if not implemented correctly

**Other Considerations**

In addition to these two approaches, another option is using **Map** functions, which are also part of the JavaScript standard library. However, they are not explicitly mentioned in this benchmark.

**Library and Special JS Features**

The provided benchmark does not use any external libraries. However, it does utilize a few special JavaScript features:

* The `\r\n` notation is used to create newline characters in the script preparation code.
* No specific JavaScript features are highlighted in the test cases, but they do demonstrate basic array operations.

**Alternatives**

Other alternatives for similar benchmarks might include:

* Using **reduce()**, another aggregation method built into the Array prototype
* Comparing performance with different sorting algorithms (e.g., quicksort, mergesort)
* Testing performance under different data sizes or distributions

Keep in mind that this benchmark is focused on demonstrating the difference between two simple approaches and does not cover more complex scenarios.
