**Benchmark Definition Json**

The benchmark definition json contains information about the benchmark itself, including its name, description, script preparation code, and HTML preparation code (which is null in this case). The script preparation code includes a set of functions to parse URLs: `parseUri`, `url_domain`, `simple_domain`, and `url_class_hostname`. These functions will be used to extract the root domain from a given URL.

**Individual Test Cases**

The individual test cases are defined in the "Test Name" field, which is repeated for each benchmark definition. Each test case has a unique name and a corresponding benchmark definition that extracts the host (root domain) from a specific URL using one of the four functions: `parseUri`, `url_domain`, `simple_domain`, or `url_class_hostname`.

**Options Compared**

The options compared in this benchmark are:

1. `parseUri`
2. `url_domain`
3. `simple_domain`
4. `url_class_hostname`

Each of these functions uses a different approach to extract the root domain from a URL.

**Pros and Cons of Each Approach**

Here's a brief overview of each approach:

1. **`parseUri`**: This function uses the `uri` module (MIT License) to parse URLs. It is more flexible and handles edge cases well, but it may be slower due to its complexity.
	* Pros: Handles edge cases well, flexible
	* Cons: Slower, more complex
2. **`url_domain`**: This function uses the `a` element of a DOM object (`document.createElement('a')`) to parse URLs. It is simple and fast, but may not handle all edge cases.
	* Pros: Fast, simple
	* Cons: May not handle edge cases
3. **`simple_domain`**: This function extracts the host from a URL using string manipulation. It is very simple and fast, but may not handle edge cases well.
	* Pros: Very fast, simple
	* Cons: May not handle edge cases
4. **`url_class_hostname`**: This function uses the `window.location.hostname` property to extract the root domain from a URL. It is similar to `simple_domain`, but uses the browser's API instead of string manipulation.
	* Pros: Fast, simple
	* Cons: May not handle edge cases

**Latest Benchmark Result**

The latest benchmark result shows that:

1. `url_class_hostname` is the fastest (with an average execution time of 258.83 ms per second).
2. `simple_domain` is close behind, with an average execution time of 133.13 ms per second.
3. `parseUri` is slower than both of these options, with an average execution time of 358.29 ms per second.
4. `url_domain` is the slowest option, with an average execution time of 482.33 ms per second.

Overall, this benchmark highlights the importance of choosing the right algorithm for extracting root domains from URLs, considering factors such as performance and edge case handling.
