Benchmark: Lodash chunk vs JS 2

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var arr = Array.from({
    length: 100000
}, () => Math.random())

Tests:

Lodash
const groups = _.chunk(arr,100)
JS
var i,j, temporary, chunk = 100; const groups = []; for (i = 0,j = arr.length; i < j; i += chunk) { groups.push(arr.slice(i, i + chunk)); // do whatever }

I'd be happy to explain the provided benchmark.

**Benchmark Overview**

The provided benchmark compares the performance of two approaches to chunking an array: using Lodash's `chunk` function and implementing it manually in JavaScript.

**Options Compared**

1. **Lodash's `chunk` function**: This approach uses a library to perform the chunking operation.
2. **Manual implementation**: This approach writes the chunking logic from scratch, without relying on any external libraries.

**Pros and Cons of Each Approach**

* **Lodash's `chunk` function**:
	+ Pros:
		- Easy to implement: simply include the Lodash library in your HTML file.
		- Well-tested and optimized for performance.
	+ Cons:
		- External dependency: requires including an extra script tag in your HTML file, which can add overhead.
		- May not be suitable for projects that require complete control over the implementation.
* **Manual implementation**:
	+ Pros:
		- Complete control over the implementation: you have full knowledge of how the chunking operation is performed.
		- No external dependency: no additional script tags are required.
	+ Cons:
		- More complex to implement: requires writing custom code for the chunking logic.
		- May be less optimized or efficient than the Lodash implementation.

**Library Used**

The `lodash.js` library is used in this benchmark. Lodash provides a set of utility functions that can simplify common tasks, such as array manipulation. In this case, the `chunk` function is used to divide an array into smaller chunks of a specified size.

**Special JS Feature or Syntax**

There are no specific JavaScript features or syntaxes mentioned in this benchmark. However, it's worth noting that some browsers may optimize certain JavaScript operations differently due to their implementation details (e.g., just-in-time compilation, caching).

**Other Alternatives**

If you're interested in exploring other approaches, here are a few alternatives:

* **Native Web APIs**: Some modern web browsers provide native APIs for array manipulation, such as `Array.prototype.slice()` or `Array.prototype.splice()`. These APIs can be used to implement the chunking operation.
* **Other libraries**: There are other libraries available that provide similar functionality to Lodash's `chunk` function, such as `underscore.js` or `ramda.js`.
* **Custom implementation using Web Assembly**: Some browsers support WebAssembly (WASM), which allows you to compile languages like C or Rust into binary instructions that can be executed by the browser. Using WASM, you could potentially write a highly optimized and efficient chunking algorithm.

I hope this explanation helps!
