Let's break down what's being tested in the provided JSON and explain the options, pros, and cons of each approach.

**Benchmark Definition**

The benchmark is testing the sorting of an object array using two different methods:

1. `fruits.sort(function(a,b){ return a.time > b.time; });`
2. `_.sortBy(fruits, "time");`

**Options compared:**

We have two options to sort the array:

a. **JavaScript Array.prototype.sort() method**: This is a built-in method that sorts the elements of an array in place, returning the sorted array. The sorting algorithm used by this method is typically Timsort, which is a hybrid sorting algorithm derived from merge sort and insertion sort.

b. **Lodash's _.sortBy() function**: This is a utility function provided by the Lodash library, which sorts the elements of an array based on a given attribute or key.

**Pros and Cons:**

a. **JavaScript Array.prototype.sort() method**:

Pros:

* Fast and efficient for small to medium-sized arrays
* Built-in method, so no additional library is required

Cons:

* Can be slow for very large arrays (due to its Timsort algorithm)
* May not perform well if the array contains duplicate values or complex data structures

b. **Lodash's _.sortBy() function**:

Pros:

* More efficient and faster than JavaScript Array.prototype.sort() method, especially for larger arrays
* Can handle complex data structures and duplicate values without issues
* Part of a larger utility library that provides other useful functions

Cons:

* Requires an additional library (Lodash) to be included in the project
* May have a slightly higher overhead due to the additional library

**Library used:**

In this benchmark, Lodash is being used as part of the "arr" test case. The `_.sortBy()` function is a key part of Lodash's utility suite, providing a convenient way to sort arrays based on various attributes or keys.

**Special JS feature/syntax:**

There are no special JavaScript features or syntaxes being tested in this benchmark. The code is straightforward and uses standard JavaScript array methods.

**Other alternatives:**

If you wanted to test other sorting algorithms or techniques, some alternatives could include:

* Using the `Array.prototype.sort()` method with a custom comparison function
* Implementing your own sorting algorithm (e.g., quicksort, mergesort)
* Using a different library or framework that provides its own sorting utilities

However, it's worth noting that JavaScript Array.prototype.sort() is generally considered a good default choice for most use cases, so unless you have specific requirements or constraints, this would likely be the preferred option.
