Benchmark: Exponentiation vs Math.pow test

Tests:

Exponentiation
let n = 50; let total = 0; for (var i = 0; i < 10000; i++) { let y = n ** 7; total += y; } console.log(total);
Math.pow
let n = 50; let total = 0; for (var i = 0; i < 10000; i++) { let y = Math.pow(n, 7); total += y; } console.log(total);

Let's break down what's being tested in this benchmark.

**Benchmark Description:**
The test is comparing the performance of two approaches to calculate `n` raised to the power of 7:

1. **Exponentiation (`**` operator)**: This uses the exponentiation operator, which is a built-in operator in JavaScript that calculates the value of `a` raised to the power of `b`.
2. **Math.pow() function**: This uses the `Math.pow()` function from the Math library, which also calculates the value of `a` raised to the power of `b`.

**Options Compared:**
The test is comparing the two approaches:

* **Exponentiation (`**` operator)** vs **Math.pow() function**

**Pros and Cons of Each Approach:**

* **Exponentiation (`**` operator)`**:
	+ Pros:
		- Typically faster than using `Math.pow()` due to its optimized implementation.
		- More concise code, making it easier to read and write.
	+ Cons:
		- May not be as flexible or customizable as using `Math.pow()`.
* **Math.pow() function**:
	+ Pros:
		- Highly customizable, allowing for more control over the calculation (e.g., rounding errors).
		- Can be useful when working with non-integer exponents or when specific rounding rules are required.
	+ Cons:
		- Typically slower than exponentiation due to its overhead and implementation details.

**Other Considerations:**

* **Library Usage:** Neither approach uses a third-party library, making the test more focused on JavaScript's built-in capabilities.
* **Special JS Features/Syntax:** Neither approach relies on any special JavaScript features or syntax beyond basic arithmetic operations.
