Script Preparation code:

var users = [
  { 'user': 'joey',  'age': 29 },
  { 'user': 'joey',  'age': 32 },
  { 'user': 'ross',    'age': 41 },
  { 'user': 'ross',    'age': 25 },

Tests:

Native sortBy
const by = (fields) => (a, b) => fields.map(o => { return a[o] > b[o] ? 1 : a[o] < b[o] ? -1 : 0; }).reduce((p, n) => p ? p : n, 0); users.sort(by(['user', 'age']));
Lodash sortBy
_.sortBy(users, ['user', 'age']);

I'll break down the provided benchmark and explain what's being tested, compared, and their pros and cons.

**Benchmark Overview**

The benchmark compares two approaches for sorting an array of objects: native JavaScript's `sort()` method versus Lodash's `sortBy()` function. The benchmark measures which approach is faster in ascending order.

**Options Compared**

Two options are compared:

1. **Native JavaScript's sort() method**: This is the built-in Array method that sorts an array of elements in place, according to a provided comparison function.
2. **Lodash's sortBy() function**: Lodash is a utility library for JavaScript that provides functional programming helpers, including `sortBy()`.

**Pros and Cons**

### Native JavaScript's sort() method

Pros:

* Fast and efficient
* Built-in method, so it's likely to be well-optimized by the browser
* Can handle large datasets efficiently

Cons:

* Requires a comparison function, which can be complex or time-consuming to implement
* May not work correctly for certain data types (e.g., strings with special characters)

### Lodash's sortBy() function

Pros:

* Convenient and easy to use
* Provides a simple and efficient way to sort arrays without requiring custom implementation
* Can handle large datasets efficiently

Cons:

* External dependency on the Lodash library, which may add overhead
* May not be as optimized as native JavaScript code for certain scenarios

**Library: Lodash**

Lodash is a popular utility library that provides a wide range of functional programming helpers. `sortBy()` is one of its most useful functions, allowing users to easily sort arrays without requiring custom implementation.

In the benchmark, Lodash's `sortBy()` function is used to sort an array of objects in ascending order based on two fields (`user` and `age`). The comparison function is not explicitly provided, as it defaults to a stable sorting algorithm that compares each field in turn.

**Special JS Feature/Syntax**

None mentioned in the benchmark definition. However, it's worth noting that Lodash uses a specific syntax for its functions (e.g., `_` prefix), which is not part of standard JavaScript.

**Alternatives**

Other alternatives for sorting arrays include:

* Other library-based functions (e.g., Moment.js for date-based sorting)
* Custom implementation using native JavaScript methods (e.g., `Array.prototype.sort()`)
* Third-party libraries or frameworks that provide built-in sorting functionality

In conclusion, the benchmark provides a useful comparison between native JavaScript's `sort()` method and Lodash's `sortBy()` function. The choice of which approach to use depends on factors like performance requirements, ease of implementation, and external dependencies.
