}

var arr = [];
for(var i = 0; i < 100000; i++){
  arr.push({value:getRandomInt(100)});

Let's dive into the explanation of what's tested in this benchmark.

**Benchmark Definition**

The benchmark is designed to compare two approaches for sorting an array: using the `_orderBy` function from Lodash and native JavaScript `sort()` method.

**Options Compared**

Two options are compared:

1. **Lodash `_orderBy`**: This function takes an array (`arr`) and returns a new sorted array based on a specified property (`'value'`). The sort order can be either ascending (`'asc'`) or descending.
2. **Native JavaScript `sort()` method**: This is a built-in method in JavaScript that sorts the elements of an array in place, returning the array itself.

**Pros and Cons**

Here are some pros and cons of each approach:

* Lodash `_orderBy`:
	+ Pros: Easy to use, concise syntax, efficient implementation.
	+ Cons: Requires the use of a third-party library (Lodash), may not be familiar to all developers.
* Native JavaScript `sort()` method:
	+ Pros: Built-in and widely supported, no additional dependencies required.
	+ Cons: More verbose syntax, less intuitive than `_orderBy`, may have performance issues if not implemented correctly.

**Library**

The Lodash library is a popular utility belt for functional programming in JavaScript. It provides a wide range of functions for various tasks, including sorting arrays.

In this benchmark, the `_.orderBy` function is used to sort the array based on the `'value'` property.

**Special JS feature or syntax**

There doesn't appear to be any special JavaScript features or syntax being used in this benchmark. However, it's worth noting that the use of Lodash requires importing a third-party library, which may not be familiar to all developers.

**Other alternatives**

If you wanted to implement an alternative sorting algorithm for this benchmark, some options could include:

* Using a custom implementation of quicksort or mergesort.
* Employing a more advanced data structure like a heap or balanced binary search tree.
* Utilizing a library like `underscore` (not Lodash) or another utility belt with similar functionality.

Keep in mind that these alternatives would require significant changes to the benchmark code and may not provide comparable results.
