Benchmark: IndexOf performance

HTML Preparation code:

<script src='https://cdn.jsdelivr.net/npm/lodash@4.17.10/lodash.min.js'></script>

Script Preparation code:

var values = [{a: 30310}, {a: 100303}, {a: 3040494}, {a: 6542321}, {a: 13123531}];
var searchValue = 6542321;

Tests:

lodash
_.findIndex(values, (v) => v.a = searchValue)

I'd be happy to explain what's being tested in the provided JSON benchmark.

**Overview**

The benchmark is designed to compare the performance of two approaches: using Lodash's `findIndex` method and the native JavaScript `findIndex` function, both with a specific search value.

**Benchmark Definitions**

There are two benchmark definitions:

1. **Lodash IndexOf**: This benchmark defines a script that creates an array of objects (`values`) and a search value (`searchValue`). The `_.findIndex` method is then called on the `values` array with a callback function that checks if the object's property `a` matches the `searchValue`. The result is expected to return the index of the matching object.

2. **IndexOf proptype**: This benchmark defines the same script and search value as above, but uses Lodash's `IndexOf` function from its `proptype` module instead of `findIndex`.

**Options Compared**

The two options being compared are:

1. **Lodash IndexOf**: Uses the `findIndex` method provided by Lodash.
2. **IndexOf proptype**: Uses a specific function from the `proptype` module within Lodash.

**Pros and Cons of Each Approach**

**Lodash IndexOf (FindIndex)**

Pros:

* Well-established, widely-used, and well-documented library with a robust ecosystem.
* Provides a familiar API for searching arrays.

Cons:

* Adds an external dependency to the benchmark script.
* May introduce unnecessary overhead due to the overhead of calling a JavaScript function.

**IndexOf proptype**

Pros:

* Uses a specific function from Lodash's `proptype` module, which might be more optimized than the general `findIndex` method.
* Could potentially provide better performance in certain scenarios.

Cons:

* Less well-known and used compared to `findIndex`.
* May require additional setup or configuration due to its specific purpose.

**Other Considerations**

* The benchmark is run on a Windows Desktop platform with Firefox 110 browser, which might affect the results. Testing on different platforms and browsers could provide more comprehensive insights.
* The script preparation code includes a specific array of objects (`values`) and search value, which might be optimized for performance in this specific case.

**Library: Lodash**

Lodash is a popular JavaScript utility library that provides various functions for tasks such as data manipulation, function composition, and string formatting. The `findIndex` method is part of Lodash's array functions, while the `IndexOf` function from the `proptype` module seems to be related to validating or checking property presence.

**Special JS Feature/Syntax**

None are explicitly mentioned in this benchmark, but it's worth noting that JavaScript features like ES6 modules (used in the script preparation code) might not be widely supported across all platforms.
