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

**Benchmark Definition**

The benchmark is defined by a JSON object with three properties:

1. `Name`: The name of the benchmark, which is "Multiply vs power operator **".
2. `Description`: A brief description of the benchmark, which compares the multiplication of `(n x n)` versus `(n ** 2)`.
3. `Script Preparation Code` and `Html Preparation Code`: These fields are empty, indicating that no custom code needs to be prepared for the benchmark.

**Individual Test Cases**

The benchmark consists of two test cases:

1. `Multiplication`: This test case measures the execution time of the expression `let x = 99 * 99;`.
2. `Power operator`: This test case measures the execution time of the expression `let x = 99 ** 2;`.

**Options Compared**

The benchmark compares two options for performing multiplication:

1. **Multiplication using the `*` operator**: The traditional way of multiplying two numbers.
2. **Exponentiation using the `**` operator**: A shorthand way of raising a number to a power.

**Pros and Cons of Each Approach**

* **Multiplication using the `*` operator**:
	+ Pros: Widely supported and well-understood by most developers.
	+ Cons: May be slower than exponentiation for large values due to the need to perform multiple multiplications.
* **Exponentiation using the `**` operator**: 
	+ Pros: Can be faster than multiplication for large values, as it reduces the number of operations required.
	+ Cons: Less intuitive and may require additional computation to verify correctness.

**Library Usage**

There is no explicit library usage in this benchmark. However, it's worth noting that the `**` operator (exponentiation) is a built-in operator in JavaScript and is not specific to any third-party library.

**Special JS Feature/Syntax**

The `**` operator (exponentiation) is a special feature of JavaScript syntax. It was introduced in ECMAScript 2015 (ES6) as a shorthand way to raise a number to a power.

**Other Alternatives**

If the benchmark were to compare alternative multiplication methods, other options could include:

* Using `Math.pow()` function: `let x = Math.pow(99, 2);`
* Using `Math.sqrt()` and `Math.pow()` together: `let sqrtX = Math.sqrt(99); let x = Math.pow(sqrtX, 2);`

However, these alternatives are not explicitly mentioned in the benchmark definition.
