Benchmark: demo arr sort and math max min

HTML Preparation code:

const arr = [10,-2,8,-45,17,-37,-39,50]

Script Preparation code:

const arr = [10,-2,8,-45,17,-37,-39,50]

Tests:

Use sort method
const arr = [10,-2,8,-45,17,-37,-39,50] sortedArr = arr.sort() const min = sortedArr[0] const max = sortedArr[arr.length - 1]
Use max min
const arr = [10,-2,8,-45,17,-37,-39,50] const min = Math.min(...arr) const max = Math.max(...arr)

Let's dive into the world of JavaScript microbenchmarks on MeasureThat.net.

**Benchmark Definition**

The benchmark definition is represented by the provided JSON, which includes:

* `Name`: A unique name for the benchmark, in this case, "demo arr sort and math max min".
* `Description`: An optional description for the benchmark, but it's empty in this case.
* `Script Preparation Code` and `Html Preparation Code`: These are code snippets that set up the environment for the benchmark. In this case, both scripts create an array of numbers: `[10,-2,8,-45,17,-37,-39,50]`.

**Individual Test Cases**

The benchmark includes two individual test cases:

1. "Use sort method"
* `Benchmark Definition`: This code snippet uses the built-in `sort()` method to sort the array and then extracts the minimum and maximum values.
* `Test Name`: The name of the test case, which is "Use sort method".

2. "Use max min"
* `Benchmark Definition`: This code snippet uses the `Math.min()` and `Math.max()` functions with the spread operator (`...`) to find the minimum and maximum values in the array without sorting it.
* `Test Name`: The name of the test case, which is "Use max min".

**Options Compared**

The two test cases compare different approaches for finding the minimum and maximum values in an array:

1. **Sort method**: This approach sorts the entire array, which can be inefficient if the array is large. It has a time complexity of O(n log n) due to the sorting.
2. **Math.min() and Math.max() with spread operator**: This approach finds the minimum and maximum values without sorting the array, making it more efficient for larger arrays. The time complexity is O(n).

**Pros and Cons**

Here's a brief summary of the pros and cons of each approach:

* **Sort method (O(n log n))**
	+ Pros: Simple to implement, easy to understand.
	+ Cons: Inefficient for large arrays, requires sorting which can be slow.
* **Math.min() and Math.max() with spread operator (O(n))**
	+ Pros: More efficient, faster execution times for larger arrays.
	+ Cons: Requires understanding of the spread operator and how it works with primitive types.

**Other Considerations**

When choosing an approach, consider the size of the array and the performance requirements. For small to medium-sized arrays, the `sort()` method might be sufficient. However, for large arrays or in applications where performance is critical, the `Math.min()` and `Math.max()` approach with the spread operator is likely a better choice.

**Library**

There are no external libraries mentioned in the benchmark definition. The `Math` library is used implicitly by the `Math.min()` and `Math.max()` functions.

**Special JS Feature or Syntax**

The spread operator (`...`) is not a special feature or syntax, but rather a built-in syntax for array expansion.

**Other Alternatives**

If you're looking for alternative approaches to find the minimum and maximum values in an array without using the `sort()` method or `Math.min()` and `Math.max()` with the spread operator:

* **Using reduce()**: You can use the `reduce()` method to find the minimum and maximum values. However, this approach still requires sorting the array internally.
* **Using bitwise operations**: There are some theoretical approaches that use bitwise operations to find the minimum and maximum values without sorting the array. However, these approaches are usually more complex and less efficient than using the spread operator.

Keep in mind that the best approach depends on your specific requirements and constraints. MeasureThat.net provides a great tool for comparing different approaches and finding the most efficient solution for your use case.
