Let's break down the benchmark and explain what's being tested.

**Overview**

The benchmark compares two approaches to iterate over an object: using `_.forOwn` from Lodash, and using native methods `Object.values` followed by `forEach`.

**Options Compared**

There are two options being compared:

1. **Lodash's `_ forOwn`**: This method calls a provided function once for each key in the specified object.
2. **Native `Object.values` + `forEach`**: This approach uses `Object.values` to get an array of the object's values, and then iterates over that array using `forEach`.

**Pros and Cons**

1. **Lodash's `_ forOwn`**:
	* Pros: Easy to read and maintain, concise syntax.
	* Cons: Additional dependency on Lodash library, potentially slower due to function call overhead.
2. **Native `Object.values` + `forEach`**:
	* Pros: Faster execution time, no additional dependencies required.
	* Cons: More verbose syntax, requires more code to achieve the same result.

**Other Considerations**

When choosing between these two approaches, consider the following:

* Performance-critical code: If speed is crucial, using native methods might be a better choice. However, in most cases, the performance difference will not be noticeable.
* Code readability and maintainability: Lodash's `_ forOwn` provides a clear and concise way to iterate over objects, making it easier to understand and modify.

**Library (Lodash)**

Lodash is a popular JavaScript utility library that provides various functions for tasks like iteration, manipulation, and transformation. In this benchmark, Lodash's `_ forOwn` method is used to iterate over the object `obj`.

**Special JS feature/Syntax**

There are no special JavaScript features or syntax mentioned in this benchmark.

**Benchmark Preparation Code**

The preparation code sets up a simple object `obj` with three properties: `a`, `b`, and `c`. The HTML preparation code includes a link to Lodash's library.

**Latest Benchmark Result**

The latest results show that the native `Object.values + forEach` approach outperforms Lodash's `_ forOwn`. However, the actual execution times are not provided, so it's difficult to determine which approach is truly faster in this specific case.
