I'd be happy to explain the benchmark being tested on MeasureThat.net.

**Overview**

The benchmark is designed to test the performance of two JavaScript functions, `a` and `b`, in different scenarios. The benchmark is prepared by providing the script preparation code and HTML preparation code (which is empty in this case).

**Script Preparation Code**

The script preparation code defines two global variables: `global` and its value `e`. Function `a` takes an optional argument `e` (defaulting to 1) and assigns its square to `global`. Function `b` also takes an optional argument `e` (defaulting to 1) and, if `e` is falsy, sets `e` to 1. Then, both functions assign the squared value of `e` to `global`.

**Options Compared**

There are two options being compared:

1. **Option 1: `a(undefined)`**
This option tests function `a` with an undefined argument.
2. **Option 2: `b(undefined)`**
This option tests function `b` with an undefined argument.

**Pros and Cons of Different Approaches**

* For Option 1 (`a(undefined)`):
	+ Pros:
		- Tests the behavior of `a` when called with an undefined value.
		- Helps identify potential issues with optional arguments or default values.
	+ Cons:
		- May not be a representative test for `a` in general, as it only tests one specific scenario.
* For Option 2 (`b(undefined)`):
	+ Pros:
		- Tests the behavior of `b` when called with an undefined value, which can help identify issues related to optional arguments or default values.
	+ Cons:
		- May not be representative of typical usage of `b`, as it only tests one specific scenario.

**Library Usage**

There is no explicit library mentioned in the script preparation code. However, some browsers may use built-in libraries for JavaScript functions like `Math.pow()` (used implicitly in `e ** 2`).

**Special JS Feature or Syntax**

None are explicitly mentioned in this benchmark.

**Other Alternatives**

If MeasureThat.net were to add more alternatives, they might consider options like:

* Using different data types (e.g., numbers, strings, objects) as arguments.
* Testing functions with and without optional arguments.
* Evaluating the performance of `a` and `b` in different environments (e.g., Node.js, browser).

Please note that these additional alternatives would require modifications to the script preparation code and test cases.
