**Overview of the Benchmark**

The provided benchmark measures the performance of two JavaScript functions: `Object.values()` and `extractValues()`. The goal is to compare the execution speed of these two functions.

**What are being compared?**

Two main approaches are being tested:

1. **`Object.values()`**: This function returns an array of a given object's own enumerable property values.
2. **`extractValues()`**: A custom function provided in the `Script Preparation Code` section, which extracts and returns an array of values from a given object.

**Pros and Cons**

* **`Object.values()`**:
	+ Pros: Widely supported across browsers, easy to implement, and efficient.
	+ Cons: May not work well with large objects or complex property names.
* **`extractValues()`**:
	+ Pros: Allows for more control over the extraction process, potentially reducing overhead.
	+ Cons: Requires custom implementation, may be less efficient than `Object.values()`, and may require additional processing.

In general, if you want a lightweight, straightforward solution that works well with most objects, `Object.values()` is likely a better choice. However, if you need more control over the extraction process or can optimize the implementation for your specific use case, `extractValues()` might be a better fit.

**Library and Special JS Feature**

No libraries are used in this benchmark. No special JavaScript features (e.g., async/await, generators) are mentioned.

**Other Alternatives**

If you need to measure the performance of different approaches, here are some alternatives:

* **`Array.prototype.reduce()`**: This function can be used as an alternative to `Object.values()`. However, it may not work well with large arrays or complex property names.
* **`for...in` loop**: You could use a traditional `for...in` loop to iterate over the object's properties and build an array. However, this approach is less efficient than `Object.values()`.

**Benchmark Preparation Code Explanation**

The `extractValues()` function takes an object as input and returns an array of its values. The implementation uses a simple `for...in` loop to iterate over the object's properties and push each value onto the `values` array.

```javascript
function extractValues(obj) {
  const values = [];
  for (var key in obj) {
    values.push(obj[key]);
  }
  return values;
}
```

This implementation has a time complexity of O(n), where n is the number of properties in the object.
