Benchmark: lodash difference vs js filter

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/lodash/4.17.10/lodash.min.js"></script>

Script Preparation code:

var arrFull = ['past','present','future']
var arrOne = ['past']

Tests:

lodash difference
_.difference(arrFull, arrOne);
js filter
arrFull.filter(x => !arrOne.includes(x));

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

**Benchmark Definition**

The benchmark is comparing two approaches to find the elements that are in `arrFull` but not in `arrOne`. The two approaches are:

1. Using the `lodash` library specifically for its `difference` function.
2. Using a simple JavaScript filter method (without any external libraries).

**Options Compared**

* **Lodash**: A popular JavaScript utility library that provides a variety of functions for tasks such as array manipulation, string manipulation, and more. The `difference` function in this case is used to find the elements that are present in one array but not in another.
* **Native JavaScript Filter Method**: A built-in method in JavaScript that allows you to filter elements from an array based on a condition.

**Pros and Cons**

* **Lodash**:
	+ Pros: Well-tested, widely used, and well-documented library. It's likely to be highly optimized for performance.
	+ Cons: Requires including an external library, which can add overhead in terms of HTTP requests and download times.
* **Native JavaScript Filter Method**:
	+ Pros: No additional libraries are required, making it a good choice for small scripts or projects where size matters.
	+ Cons: May not be as efficient as the `lodash` implementation due to its native nature.

**Other Considerations**

* The benchmark is comparing two different approaches, which allows users to compare performance characteristics of each method.
* The use of real-world values in the script preparation code (`arrFull` and `arrOne`) makes it easier to understand how each method performs in a practical scenario.

**Library: Lodash**

Lodash is a popular JavaScript utility library that provides a wide range of functions for tasks such as array manipulation, string manipulation, and more. The `difference` function in this case is used to find the elements that are present in one array but not in another.

The `lodash` library includes many features that make it efficient and reliable, such as:

* Well-optimized algorithms
* High-quality documentation and examples
* A large community of users and contributors

However, including an external library like Lodash also adds some overhead due to HTTP requests and download times.

**Special JS Feature: none**

There are no special JavaScript features or syntaxes being tested in this benchmark. The test cases focus solely on comparing the performance of two different approaches to find elements that are not common between two arrays.

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