Benchmark: Deduplicate 2 - MeasureThat.net

Tests:

Sort
let array = []; for (let i = 0; i < 100000; i++) { array.push(1); array.push(i); } array.sort(); let newArray = [array[0]]; for(let i = 0; i < array.length; i ++) { if(array[i-1] !== array[i]) { newArray.push(array[i]) } } console.log(newArray);
Set
let array = []; for (let i = 0; i < 100000; i++) { array.push(1); array.push(i); } console.log([...new Set(array)]);

I'll break down the benchmark and its options, pros, and cons.

**Benchmark Overview**

The benchmark tests two JavaScript algorithms:

1. **Deduplicate 2**: Sorts an array of 100,000 elements, removes duplicates, and logs the resulting array to the console.
2. **Set**: Creates a new Set from an array of 100,000 elements (all ones) and logs it.

**Options Compared**

The benchmark compares two approaches:

1. **Sort Algorithm**: Sorts the array using the built-in `sort()` method and then removes duplicates by comparing adjacent elements in the sorted array.
2. **Set Data Structure**: Creates a new Set from the array, which automatically removes duplicates since sets only store unique values.

**Pros and Cons of Each Approach**

1. **Sort Algorithm**:
	* Pros:
		+ Simple to implement (just two lines of code).
		+ Works on any JavaScript engine.
	* Cons:
		+ Has a time complexity of O(n log n) due to the `sort()` method, which can be slow for large datasets.
		+ Requires extra memory to store the temporary sorted array.
2. **Set Data Structure**:
	* Pros:
		+ Has a time complexity of O(n), making it faster than the sort algorithm for large datasets.
		+ Uses less memory since sets only store unique values.
	* Cons:
		+ Not all JavaScript engines support Set data structures (only modern browsers and some Node.js versions).
		+ May not work in older or non-standard JavaScript environments.

**Library Used**

In the benchmark, the `Set` function is used from the built-in JavaScript language. The `Set` data structure was introduced in ECMAScript 2015 (ES6) as part of the JavaScript standard.

**Special JS Features/Syntax**

None mentioned in this specific benchmark, but it's worth noting that other benchmarks might use features like async/await, Promises, or modern syntax like destructuring and arrow functions.
