The provided benchmark tests three different ways to calculate the result of `71^3` in JavaScript:

1. **Exponentiation (`**`)**: This is the built-in operator in JavaScript for exponentiation. It's used as `y = 71 ** 3`.

Pros: Fast and efficient, directly implemented in the JavaScript engine.
Cons: May not be optimized for all browsers or devices.

2. **Explicit Multiply (`* * *`)**: In this approach, we calculate the result by multiplying `71` with itself three times: `z = 71 * 71 * 71`.

Pros: More readable and maintainable code, allows for easier debugging.
Cons: Slower than exponentiation due to repeated multiplication.

3. **`Math.pow()` function**: The `Math.pow()` function takes two arguments: the base and the exponent. It returns the value of the expression `base ^ exponent`. In this benchmark, it's used as `x = Math.pow(71, 3)`.

Pros: General-purpose function for calculating any power, can handle fractional exponents.
Cons: May be slower than exponentiation due to additional overhead.

The choice of approach depends on the specific use case and performance requirements. If speed is critical and readability is not a concern, using the built-in exponentiation operator (`**`) or `Math.pow()` function may be the best choice. However, if code readability and maintainability are important, using explicit multiplication with three multiplies (`* * *`) might be a better option.

It's worth noting that the benchmark results show Chrome 93 on Chrome OS 14092.77.0 executing each test case at different speeds, which indicates potential browser or device-specific performance variations.
