Benchmark: To the 7th power v2

Script Preparation code:

var result;
var num = 9.87;


function pow7 (x) {
 	const x2 = x * x;
 	const x7 = x2 * x2 * x2 * x;
 	return x7;
 }

function pow27 (x) {
 	const x2 = x * x;
 	return x2 * x2 * x2 * x
 }

function pow37 (x) {
  const x3 = x * x * x;
  return x3 * x3 * x
}

function powMult7 (x) {
  return x*x*x*x*x*x*x
}

Tests:

Using the pow7() function
result = pow7(num);
Using the ** operator
result = num ** 7;
Using Math.pow()
result = Math.pow(num,7);
Multiplying seven times
result = num * num * num * num * num * num * num;
Using the pow27() function
result = pow27(num);
Using the pow37() function
result = pow37(num);
Using the powMult7() function
result = powMult7(num);

Let's break down the benchmark and explain what's being tested, compared options, pros and cons, library usage, special JS features, and other considerations.

**Benchmark Overview**

The benchmark is designed to compare different ways to raise a number to the power of 7. The test case involves calculating `x^7` for a given input value `num`. The benchmark has six test cases:

1. Using the `pow7()` function
2. Using the `**` operator (exponentiation)
3. Using the `Math.pow()` method
4. Multiplying the number by itself seven times
5. Using the `pow27()` function
6. Using the `pow37()` function

**Comparison Options**

The benchmark compares different approaches to calculate `x^7`. Here's a brief overview of each option:

1. **`pow7()` function**: A custom implementation of exponentiation using repeated multiplication.
2. **`**` operator (exponentiation)**: The built-in exponentiation operator in JavaScript, which uses the `POW` instruction on x86 processors or more efficient algorithms on other architectures.
3. **`Math.pow()` method**: A built-in method in the `Math` object for calculating powers.
4. **Multiplying by itself seven times**: A simple implementation using repeated multiplication.

**Pros and Cons**

Each approach has its pros and cons:

1. **`pow7()` function**: Pros: easy to understand, customizable. Cons: may be slower due to repeated multiplication.
2. **`**` operator (exponentiation)**: Pros: fast, efficient. Cons: not customizable, relies on underlying processor instructions.
3. **`Math.pow()` method**: Pros: built-in, reliable. Cons: may use more memory or be slower than the `**` operator due to overhead.
4. **Multiplying by itself seven times**: Pros: simple, easy to understand. Cons: slow and inefficient.

**Library Usage**

The benchmark uses two libraries:

1. **None**: The test cases are pure JavaScript functions.
2. **Math**: The `Math.pow()` method is used in one of the test cases.

**Special JS Features**

There are no special JavaScript features mentioned in this benchmark, such as ES6 syntax or async/await.

**Other Considerations**

The benchmark also takes into account:

1. **Browser variations**: The benchmark uses a single browser (Safari 15) to ensure consistent results.
2. **Device platform and OS**: The benchmark runs on macOS Desktop to isolate the test from other factors.
3. **Execution count**: The benchmark measures the number of executions per second, which indicates performance.

**Alternatives**

If you want to compare different approaches to calculate `x^7`, you could add more test cases, such as:

1. Using a third-party library for exponentiation (e.g., `exponent.js`)
2. Implementing exponentiation using bitwise operations
3. Comparing the performance of different CPU instructions (e.g., `POW` vs. `MUL`)

By adding these alternative approaches, you can gain a deeper understanding of how different methods compare in terms of performance and efficiency.
