Benchmark: Chunk - lodash vs native

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.4/lodash.min.js"></script>

Script Preparation code:

var values = new Array(200 * 200 * 4);

Tests:

lodash
var chunks = _.chunk(values, 4);
native
var chunks = []; for (var i = 0; i < values.length; i += 4) { chunks.push(values.slice(i, i + 4)); }

Let's break down the benchmark and explain what's being tested.

**Benchmark Definition**

The benchmark is designed to compare the performance of two approaches:

1. Using Lodash, a popular JavaScript utility library.
2. Implementing the chunking logic manually (without using any external libraries).

**Options Compared**

Two options are compared:

* **Lodash**: A library that provides various utility functions for tasks such as string manipulation, array and object management, and more. In this benchmark, Lodash is used to implement the `chunk` function, which splits an array into smaller chunks.
* **Native Implementation**: A manual implementation of the chunking logic using JavaScript's built-in features.

**Pros and Cons**

Here are some pros and cons of each approach:

* **Lodash**:
	+ Pros: Provides a well-tested and optimized implementation, reduces code size and readability, and can be reused in other projects.
	+ Cons: Requires an additional library download, which may impact performance if not cached or minified properly. Additionally, the benchmarked code is less maintainable since it's not part of the main JavaScript runtime.
* **Native Implementation**:
	+ Pros: No external dependencies, maintains control over the implementation, and allows for easy optimization and debugging.
	+ Cons: Requires more code and manual maintenance, which can lead to errors or bugs.

**Library (Lodash)**

Lodash is a popular JavaScript utility library that provides various functions for tasks such as:

* String manipulation
* Array and object management
* Math and statistics operations
* Functionality like `chunk` (which is used in this benchmark)

Lodash's purpose is to provide a set of reusable functions that can simplify code and improve performance. In the context of this benchmark, Lodash's implementation of the `chunk` function is used to compare its performance with a native implementation.

**Special JS Feature/ Syntax**

There isn't any special JavaScript feature or syntax being tested in this benchmark. The code uses standard JavaScript features like arrays, loops, and function calls.

**Other Alternatives**

If you're looking for alternative approaches to chunking an array, some options include:

* Using `Array.prototype.reduce()` or `Array.prototype.forEach()`
* Implementing a custom loop-based solution
* Utilizing specialized libraries like Ramda or Underscore.js

Keep in mind that each approach has its own trade-offs and use cases. This benchmark aims to compare the performance of Lodash's implementation with a native implementation, providing a baseline for other approaches.

I hope this explanation helps! Let me know if you have any further questions.
