Tests:

Underscore sortBy()
_.sortBy(users, 'name')
Vanilla sort()
users.sort(sortBy("name"));
Vanilla CUSTOM sort method
insertionSort(users, "name");

This benchmark compares four different methods of sorting an array of user objects by their `name` property in JavaScript:

**Options Compared:**

1. **Underscore _.sortBy()**: This uses the `_.sortBy()` function from the Underscore.js library, a popular utility library for JavaScript. It provides a convenient and concise way to sort arrays based on one or more properties.

2. **Vanilla .sort() with custom comparison function**:  This method utilizes the built-in `sort()` method of arrays in JavaScript and passes a custom comparison function that defines how to compare elements. This approach gives you fine-grained control over the sorting logic.

3. **Vanilla CUSTOM sort method**: This test implements a basic insertion sort algorithm, which is a relatively simple sorting algorithm known for its performance in certain scenarios. It's defined within the benchmark code and directly compares objects based on the `name` property.

4. **Vanilla .sort() with localeCompare**:  This uses the built-in `localeCompare()` method to compare strings based on their locale, potentially handling different languages and character encodings more accurately.

**Pros and Cons:**

* **Underscore _.sortBy()**: 
    * **Pro**:  Very concise and readable syntax, leveraging a well-established library.
    * **Con**:  Requires including the Underscore.js library, which adds to bundle size and potential loading time.

* **Vanilla .sort() with custom comparison function**:
    * **Pro**:  Flexible control over sorting logic, allowing for complex comparisons or custom rules. 
    * **Con**: Can become more verbose than other options if the comparison logic is intricate.

* **Vanilla CUSTOM sort method (Insertion Sort)**:
    * **Pro**: Potentially efficient in certain cases, especially with small datasets or partially sorted data.
    * **Con**: Not always the most performant algorithm for large datasets; can be more complex to implement than other options.

* **Vanilla .sort() with localeCompare**:
    * **Pro**:  Handles locale-specific sorting for potentially more accurate results across different languages.
    * **Con**: Can be slightly slower than simpler comparison methods in some cases.

**Other Considerations:**

* **Dataset Size**: The performance of each method can vary significantly depending on the size of the dataset being sorted. 
* **Sorting Complexity**: If you need to sort based on multiple properties or apply complex sorting rules, a custom comparison function might be the most suitable option.
