Benchmark: Lodash.js vs Native 2

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.4/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
arr2.forEach(function (element, index) { element = element*2; });
Lodash.js filter
_.each(arr2, function (element, index) { element = element*2; });

Let's break down what's being tested in the provided JSON benchmark.

**Benchmark Definition**

The benchmark measures the performance of two approaches:

1. **Native**: The native JavaScript implementation, which does not require any external libraries.
2. **Lodash.js filter**: A specific function from the Lodash library, which is a popular utility library for JavaScript. In this case, it's being used to iterate over an array and perform a simple transformation on each element.

**Options Compared**

The two options are compared in terms of their performance (measured by the number of executions per second). The benchmark script creates three arrays with different sizes: 100,000, 10,000,000, and 100,000,000 elements. It then performs a simple transformation on each element in each array using the `forEach` method for Native and the `_each` function from Lodash.js.

**Pros and Cons**

* **Native**: The native JavaScript implementation has the advantage of being highly optimized and directly executed by the engine, which can result in better performance. However, it may not be as concise or readable as other approaches.
* **Lodash.js filter**: Using a library like Lodash.js provides a more concise and readable way to perform common tasks. However, it requires an additional dependency and may introduce overhead due to the need for loading and parsing the library.

**Library: Lodash.js**

Lodash is a popular JavaScript utility library that provides a wide range of functions for common tasks such as:

* Array manipulation (e.g., `_each`, `_forEach`)
* String manipulation (e.g., `upperCase`, `camelCase`)
* Object manipulation (e.g., `assignIn`, `pick`)
* Functional programming utilities (e.g., `map`, `filter`, `reduce`)

The `_each` function in this benchmark is used to iterate over an array and perform a transformation on each element.

**Special JS Feature/Syntax**

There is no special JavaScript feature or syntax being tested in this benchmark. However, it's worth noting that the use of `forEach` and `_.each` implies support for the modern JavaScript `for...of` loop and the Lodash library, respectively.

**Other Alternatives**

If you're looking for alternative libraries to perform array transformations, some popular options include:

* **Underscore.js**: A minimalist utility library similar to Lodash.
* **Ramda**: A functional programming library that provides a different set of utilities and abstractions.
* **Array.prototype.forEach()`: The built-in JavaScript method used in the Native implementation.

Keep in mind that each alternative has its own strengths, weaknesses, and use cases.
