Benchmark: lodash vs native performance

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.12/lodash.min.js"></script>

Script Preparation code:

var max1 = 100000; // 100,000 (100 Thousand)
var max2 = 10000000; // 10,000,000 (10 Million)
var max3 = 100000000; // 100,000,000 (100 Million)

var arr1 = [];
//for (var i = 0; i <= max1; i++) { arr1.push(i); }

var arr2 = [];
for (var i = 0; i <= max2; i++) { arr2.push(i); }

var arr3 = [];
//for (var i = 0; i <= max3; i++) { arr3.push(i); }

Tests:

Native forEach
arr2.forEach((element) => element*2);
lodash
_.forEach(arr2, (element) => element*2);
Native for
for (const element of arr2) { element*2 }

Let's break down the provided benchmark and its components.

**Benchmark Definition JSON**

The benchmark definition is a JSON object that contains information about the test case. The key highlights are:

* `Name`: "lodash vs native performance" - This is the name of the benchmark, which describes the comparison between Lodash (a popular JavaScript utility library) and native JavaScript performance.
* `Script Preparation Code`: This section contains code snippets used to prepare the input data for the test cases. In this case, there are three arrays (`arr1`, `arr2`, and `arr3`) that will be used to test different operations:
	+ `arr1` is populated with numbers from 0 to `max1` (100,000).
	+ `arr2` is populated with numbers from 0 to `max2` (10,000,000).
	+ `arr3` is populated with numbers from 0 to `max3` (100,000,000).
* `Html Preparation Code`: This section contains the JavaScript file URL for Lodash, which will be used in the test cases.

**Individual Test Cases**

The benchmark definition includes three individual test cases, each represented as a separate JSON object. The key highlights are:

* Each test case has a unique `Benchmark Definition` string that describes the operation to be performed on the input arrays.
	+ "arr2.forEach((element) => element*2);" tests the native `forEach` method with a callback function that multiplies each element by 2.
	+ "_.forEach(arr2, (element) => element*2);" tests the Lodash `forEach` method with a callback function that multiplies each element by 2.
	+ "for (const element of arr2) { element*2 }" tests the native `for...of` loop syntax with an arrow function that multiplies each element by 2.

**Library: Lodash**

Lodash is a popular JavaScript utility library that provides a comprehensive set of functions for various tasks, such as array manipulation, string manipulation, and more. In this benchmark, Lodash is used to test the performance of its `forEach` method.

The purpose of using Lodash in this benchmark is to compare its performance with native JavaScript implementations.

**Pros and Cons**

* **Lodash:**
	+ Pros:
		- Well-maintained and widely adopted.
		- Provides a convenient and consistent API for various tasks.
	+ Cons:
		- Adds overhead due to the need to import and execute the library.
		- May not be optimized for performance in certain use cases.
* **Native JavaScript:**
	+ Pros:
		- Optimized for performance by the JavaScript engine.
		- Does not add any extra overhead or dependencies.
	+ Cons:
		- Requires manual implementation of the loop or array manipulation logic.

**Special JS Feature/Syntax**

There are no special JavaScript features or syntaxes used in this benchmark. The test cases only utilize standard JavaScript operators and control structures.

**Other Alternatives**

If you're looking for alternative approaches to benchmarking performance, here are a few options:

* **Benchmarking frameworks:** Tools like Benchmark.js, Microbenchmark, or WebPerf can help you create and run benchmarks more efficiently.
* **Native JavaScript alternatives:** If you want to compare the performance of different native JavaScript implementations (e.g., V8 vs. SpiderMonkey), you can use specialized benchmarking tools like Native Instruments' Jitter or Google's V8 Benchmark.
* **Custom implementation:** You can also write your own custom benchmarking code to test specific scenarios and libraries.

Keep in mind that each approach has its strengths and weaknesses, and the choice of which one to use depends on your specific needs and goals.
