Benchmark: native sort of objects by localeCompare vs own compare function

Script Preparation code:

var users = [
  { 'user': 'joey',  'age': 32 },
  { 'user': 'ross',    'age': 41 },
  { 'user': 'chandler', 'age': 39 }
]

Tests:

native sort of objects by localeCompare
users.sort((a,b) => a.user.localeCompare(b.user));
own compare function
users.sort((a,b) => { if (a.user > b.user) return 1; if (a.user < b.user) return -1; return 0; });

Let's break down the benchmark and its options.

**Benchmark Description**

The benchmark compares two approaches to sorting an array of objects: using the `localeCompare` method native to JavaScript (also known as "native sort") versus creating an own compare function.

**Options Being Compared**

There are two options being compared:

1. **Native Sort with localeCompare**: This approach uses the built-in `localeCompare` method, which is a part of the ECMAScript standard and is implemented by most browsers. The `localeCompare` method compares strings in a way that takes into account the user's locale settings.
2. **Own Compare Function**: This approach requires defining an own compare function to sort the array. In this case, the compare function simply checks if the "user" property of each object is greater than or less than the other, and returns 1, -1, or 0 accordingly.

**Pros and Cons**

**Native Sort with localeCompare:**

Pros:

* Easy to use and implement
* Takes into account user's locale settings for string comparisons
* Most browsers support it

Cons:

* May have performance issues if not optimized (e.g., comparing strings that are not in the same language)
* Limited control over comparison logic

**Own Compare Function:**

Pros:

* Provides more control over comparison logic
* Can be optimized for specific use cases

Cons:

* Requires defining an own compare function, which can be error-prone and harder to read
* Does not take into account user's locale settings by default

**Library Used (if any)**

In this benchmark, no libraries are explicitly mentioned.

**Special JS Feature or Syntax**

There is a special syntax used in the `Benchmark Definition` json: `(a,b) => { ... }`. This is an arrow function expression, which is a shorthand way of defining small anonymous functions. It's a modern JavaScript feature that's widely supported by most browsers and engines.

**Other Alternatives**

If you wanted to implement this benchmark yourself, here are some alternatives:

* Using the `Array.prototype.sort()` method with a custom compare function (e.g., using an arrow function or a traditional function).
* Implementing a sorting algorithm from scratch (e.g., merge sort, quicksort).
* Using a library like Lodash or Moment.js to simplify string comparisons.
* Using a different approach, such as using a data structure that's inherently sorted (e.g., a binary search tree).

Keep in mind that the benchmark is designed to compare performance between two specific approaches, so implementing alternative solutions would likely require significant changes.
