Benchmark: ~~(12.34) vs split()

Script Preparation code:

let a = ~~(12.34);
let b = Number(String(12.34).split('.')[0]);
console.log(a);
console.log(b);

Tests:

~~(12.34)
let a = ~~(12.34);
split()
let b = Number(String(12.34).split('.')[0]);

Let's break down the benchmark and its various components.

**Benchmark Definition**

The benchmark definition is provided in JSON format, which includes:

* `Name`: The name of the benchmark, e.g., "~~(12.34) vs split()"
* `Description`: An empty description for this benchmark (not provided)
* `Script Preparation Code`: A JavaScript snippet that prepares the environment for the benchmark:
```javascript
let a = ~~(12.34);
let b = Number(String(12.34).split('.')[0]);
console.log(a);
console.log(b);
```
This code sets up two variables, `a` and `b`, using the bitwise truncation operator (`~~`) and the `Number` function with string splitting. The `console.log` statements print the results to the console.

* `Html Preparation Code`: An empty HTML snippet (not provided)

**Individual Test Cases**

The benchmark consists of two individual test cases:

1. `~~(12.34)`
2. `split()`

Each test case has its own benchmark definition, which is simply a subset of the script preparation code.

**Options Being Compared**

In this benchmark, two options are being compared:

* **Bitwise Truncation Operator (`~~`)**: This operator truncates the number 12.34 to an integer value.
* **String Splitting with `Number` Function and String Formatting**: This approach involves converting the number 12.34 to a string, splitting it at the decimal point using the dot (.) character as the separator, taking the first part of the resulting array, and then passing that string to the `Number` function to convert it back to an integer.

**Pros and Cons**

Here's a brief summary of the pros and cons of each approach:

* **Bitwise Truncation Operator (`~~`)**:
	+ Pros: Simple, efficient, and widely supported in JavaScript engines.
	+ Cons: May not be suitable for all numeric formats (e.g., negative numbers or non-integer values).
* **String Splitting with `Number` Function and String Formatting**:
	+ Pros: More flexible than bitwise truncation operator, can handle decimal points, and provides a clear way to extract the integer part.
	+ Cons: May be slower due to string manipulation and formatting.

**Library Used**

In this benchmark, the `Number` function is used from the JavaScript standard library. Its purpose is to convert a numeric value or string representation of a number to its corresponding numeric value.

**Special JS Feature or Syntax**

There are no special JavaScript features or syntax mentioned in this benchmark. It only uses standard JavaScript operators and functions.

**Other Alternatives**

Alternative approaches to compare with these two options could include:

* Using `Math.trunc()` instead of the bitwise truncation operator.
* Utilizing libraries like `lodash` or `mathjs` that provide alternative methods for rounding numbers.
* Implementing custom rounding algorithms using loops or recursive function calls.

Keep in mind that the choice of approach depends on the specific requirements and constraints of your use case.
