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

**Benchmark Overview**

The benchmark compares two approaches: using Lodash's `isEqual` function to compare arrays, and using the `join` method with a separator to compare arrays. The goal is to determine which approach is faster.

**Options Compared**

The benchmark tests the following options:

1. **Lodash isEqual**: This function takes two arrays as input and returns a boolean indicating whether they are equal.
2. **Join Method with Separator**: This method concatenates the elements of an array into a string, using a specified separator (in this case, `"|"`).

**Pros and Cons**

* **Lodash isEqual**:
	+ Pros: Easy to use, well-tested, and widely supported.
	+ Cons: May not be optimized for performance, may require additional dependencies (Lodash).
* **Join Method with Separator**:
	+ Pros: Lightweight, no dependencies required. However, it may not be as robust or flexible as the `isEqual` function.
	+ Cons: Can be slower than `isEqual` due to string concatenation.

**Library and Purpose**

The Lodash library is a popular utility library for JavaScript that provides various functions for common tasks, such as array manipulation, object manipulation, and more. In this benchmark, Lodash's `isEqual` function is used to compare arrays.

**Special JS Feature or Syntax**

None of the test cases use any special JavaScript features or syntax that are not widely supported.

**Other Alternatives**

If you need to compare arrays, other alternatives to Lodash's `isEqual` include:

* **Array.prototype.every() and Array.prototype.some()**: These methods can be used to check if all or some elements in an array satisfy a condition.
* **ES6 Arrays with `every()` and `some()`**: If you're using modern JavaScript (ECMAScript 2015+), you can use the built-in `every()` and `some()` methods on arrays.

**Benchmark Preparation Code**

The provided script preparation code sets up two global variables, `foo1` and `bar1`, which are arrays with some identical elements.

The HTML preparation code includes a script tag that loads Lodash version 4.17.4 from a CDN.

**Individual Test Cases**

The benchmark consists of two test cases:

1. **_.isEqual Level 1**: This test case uses the Lodash `isEqual` function to compare the `foo1` and `bar1` arrays.
2. **join Level 1**: This test case uses the `join` method with a separator to concatenate the elements of the `foo1` and `bar1` arrays.

The benchmark measures the execution time of each test case, providing insight into which approach is faster for array comparison.
