Benchmark: Lodash.js vs Native forked

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
_.forEach(arr2, function (element, index) { element = element*2; });

I'll break down the provided benchmark definition and test cases to help you understand what's being tested.

**Benchmark Definition**

The benchmark measures the performance difference between two approaches: using Lodash.js and using native JavaScript functions for array operations.

The script preparation code creates three arrays (`arr1`, `arr2`, and `arr3`) with different sizes (100,000, 10,000,000, and 100,000,000 elements, respectively). This is done to test the performance of the benchmark on large datasets.

**Test Cases**

There are two individual test cases:

1. **Native**: This test case uses native JavaScript functions (`forEach`) to perform the required operation on `arr2`. The operation multiplies each element by 2.
2. **Lodash.js filter**: This test case uses Lodash.js's `_.forEach` function (specifically, the `filter` method) to perform the same operation on `arr2`.

**Options Compared**

The benchmark compares two options:

* **Native JavaScript functions** (using `forEach`)
* **Lodash.js functions** (`_._forEach`)

**Pros and Cons of Each Approach**

**Native JavaScript Functions**

Pros:

* Typically faster since it doesn't involve function call overhead
* Can be optimized by the browser's Just-In-Time (JIT) compiler

Cons:

* Requires manual handling of array iteration, which can lead to more code and potential errors
* May not work well with large datasets due to performance issues

**Lodash.js Functions**

Pros:

* Easier to write and maintain since it abstracts away low-level details
* Provides additional functionality (e.g., filtering) that might be useful in certain scenarios

Cons:

* Involves function call overhead, which can reduce performance
* Requires importing the Lodash library, adding extra size and potential latency

**Library: Lodash.js**

Lodash.js is a popular JavaScript utility library that provides a wide range of functions for tasks such as array manipulation, string manipulation, and functional programming. The `_.forEach` function used in this benchmark is part of the Lodash.js library.

**Special JS Feature/Syntax (Not Applicable)**

There are no special JavaScript features or syntax mentioned in this benchmark.

**Alternatives**

Other alternatives to Lodash.js for array operations include:

* **Underscore.js**: Another popular utility library that provides similar functionality to Lodash.js.
* **Array.prototype.forEach()`: Using the built-in `forEach` method on arrays, which can be faster than using a library function but requires more manual handling of iteration.
* **Custom implementations**: Writing custom functions for array operations can provide optimal performance and control, but may require more code and expertise.

In summary, this benchmark compares the performance of two approaches: native JavaScript functions (`forEach`) and Lodash.js functions (`_.forEach`). The choice between these options depends on the specific use case, performance requirements, and personal preference.
