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

**Benchmark Overview**

The benchmark is designed to compare the performance of two approaches: using the Lodash library's `filter` method versus the native JavaScript array `filter` method in ES6.

**Options Being Compared**

Two options are being compared:

1. **Lodash Filter Method**: This uses the popular utility library, Lodash, which provides a `filter` function that can be used to filter arrays.
2. **Native JavaScript Array Filter Method (ES6)**: This uses the native JavaScript array method `filter`, introduced in ES6, to filter arrays.

**Pros and Cons of Each Approach**

1. **Lodash Filter Method**
	* Pros:
		+ Provides a simple and consistent API for filtering arrays.
		+ Can be used with any type of data structure that supports filtering.
	* Cons:
		+ Adds an additional dependency (the Lodash library) to the benchmark, which may affect performance.
		+ May have overhead due to the complexity of the utility library.
2. **Native JavaScript Array Filter Method (ES6)**
	* Pros:
		+ No additional dependencies or overhead.
		+ Optimized for performance and native code execution.
	* Cons:
		+ Requires ES6 compatibility, which may not be supported in older browsers.
		+ May have a steeper learning curve due to the use of modern JavaScript features.

**Library: Lodash**

Lodash is a popular utility library that provides a wide range of functions for working with arrays, objects, and other data structures. The `filter` function is one of its most commonly used methods. By using Lodash's `filter` method, the benchmark takes advantage of the library's optimized implementation and avoids having to implement filtering logic manually.

**Special JS Feature/ Syntax: ES6**

The benchmark uses ES6 syntax for defining the array filter method, which includes features like arrow functions (`arr => arr.age > 26`) and template literals (`'\r\n  { 'name': 'lim', 'age': 26 }\r\n'`). This is a newer syntax introduced in ES6 that allows for more concise and expressive code.

**Other Alternatives**

If you wanted to modify or extend this benchmark, here are some alternative approaches you could consider:

1. **Use other utility libraries**: Instead of using Lodash, you could use other popular JavaScript utility libraries like Moment.js or Underscore.js.
2. **Implement filtering logic manually**: You could implement the filtering logic manually, without relying on a library or native JavaScript method.
3. **Use different data structures**: You could modify the benchmark to use different data structures, such as objects or sets, and compare the performance of the `filter` method for each one.

Overall, this benchmark provides a simple and effective way to compare the performance of two approaches: using Lodash's `filter` method versus the native JavaScript array `filter` method in ES6.
