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

**Benchmark Overview**

The benchmark is designed to compare the performance of two Lodash functions: `sortBy` and `orderBy`. Both functions are used to sort an array in ascending order, but they have different implementation details.

**Options Compared**

The benchmark compares two approaches:

1. **Lodash `sortBy`**: This function sorts the array based on a specified key (`"value"` in this case).
2. **Lodash `orderBy`**: This function also sorts the array in ascending order, but it doesn't take a specific key as an argument.

**Pros and Cons of Each Approach**

1. **Lodash `sortBy`**:
	* Pros:
		+ Allows for sorting based on a specific key.
		+ Can be more efficient if the sorting is stable (i.e., maintains the original order of equal elements).
	* Cons:
		+ May require additional memory allocations or copies of the array if not implemented efficiently.
2. **Lodash `orderBy`**:
	* Pros:
		+ Is often implemented more efficiently, as it doesn't need to consider multiple keys.
		+ Can be faster for large datasets since it's typically a single pass through the array.
	* Cons:
		+ Does not allow for sorting based on specific keys.

**Library and Purpose**

The Lodash library is a popular utility library for JavaScript that provides a wide range of functions for tasks like array manipulation, string trimming, and more. In this benchmark, Lodash is used to provide the `sortBy` and `orderBy` functions, which are then compared in terms of performance.

**Special JS Feature or Syntax**

There doesn't seem to be any special JavaScript features or syntax used in this benchmark that's not widely supported by modern browsers.

**Other Alternatives**

If you're looking for alternative sorting libraries or implementations, some popular options include:

* **Array.prototype.sort()**: A built-in method of the Array prototype, which sorts the array in-place.
* **Moment.js**: A library specifically designed for date and time manipulation, but also includes a sorting function.
* **Ramda**: A functional programming library that provides various utility functions, including sorting.

Keep in mind that each alternative has its own strengths and weaknesses, and the choice of implementation will depend on your specific use case and requirements.
