Let's break down what's being tested in this benchmark.

**What is being tested?**

The benchmark is comparing the performance of two functions: `_.max(arr)` from Lodash and `Math.max(...arr)`. Both functions are used to find the maximum value in an array.

**Options compared**

There are two options being compared:

1. **Lodash's `_max` function**: This function is part of the Lodash library, a popular utility library for JavaScript.
2. **JavaScript's built-in `Math.max` function**: This is a standard function in JavaScript that can be used to find the maximum value in an array.

**Pros and Cons of each approach**

1. **Lodash's `_max` function**:
	* Pros: Lodash is a well-maintained library with extensive documentation, making it easy to use and understand.
	* Cons: It adds additional overhead due to the need for a separate library, which might not be ideal for small scripts or projects where size matters.
2. **JavaScript's built-in `Math.max` function**:
	* Pros: This approach is lightweight and doesn't require an additional library, making it suitable for smaller projects or those with strict size constraints.
	* Cons: The implementation of `Math.max` might not be as efficient as Lodash's `_max` function in certain cases.

**Library description**

Lodash is a JavaScript utility library that provides a lot of useful functions for tasks like array manipulation, string handling, and more. The `_max` function is one of its many utility functions that can be used to find the maximum value in an array.

**Special JS feature or syntax**

There are no special JS features or syntaxes mentioned in this benchmark. However, it's worth noting that the use of `...args` in the `Math.max` implementation (in the HTML preparation code) is a modern JavaScript feature called "spread syntax" that allows for concise array notation.

**Other alternatives**

If you wanted to compare other implementations of the `max` function, you might consider:

1. **Using a custom implementation**: Writing your own `max` function from scratch using JavaScript's built-in functions like `reduce` or `forEach`.
2. **Using another library**: Other libraries like Moment.js (for date-related operations) or Underscore.js (similar to Lodash, but with some differences in its API).

Keep in mind that the benchmark is focused on comparing Lodash's `_max` function and JavaScript's built-in `Math.max` function specifically.
