Benchmark: Random ID generate

Script Preparation code:

window.generateUUID = () => {
    return Math.random().toString(36).substring(2, 15) + Math.random().toString(36).substring(2, 15);
};

window.generateID = (stringLength = 22) => {
    let randomStr = "";
    const characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZqeytrpolkadjsghfgmnbzxcvnQPOWEYRKASJHDGFMNBCVX--___-_jsfhrlg-_124903564576986483658fgh4sdfh687e4h897WETHJ68F7G4688471877GFHJFFGJ87469857468746hfghwrtiyj4598yhdjkhgnk";
    for (let index = 0; index < stringLength; index++) {
      randomStr += characters.charAt(
        Math.floor(Math.random() * characters.length)
      );
    }
    return randomStr;
  };

Let's break down the benchmark and its test cases.

**Benchmark Definition**

The benchmark is designed to measure the performance of generating random UUIDs (Universally Unique Identifiers). The script defines two functions: `generateUUID` and `generateID`. Both functions are intended to generate random strings, but they use different approaches:

1. `generateUUID`: This function uses the `crypto.randomUUID()` method, which is a built-in function in Node.js that generates a cryptographically secure UUID.
2. `generateID`: This function generates a random string using a predefined character set and concatenates it with a random length.

**Options Compared**

The benchmark compares three different approaches:

1. **`crypto.randomUUID()`**: This method uses the `crypto` module to generate a cryptographically secure UUID. It is considered the most secure option.
2. **Custom `generateUUID` function**: This function generates a random string using a predefined character set and concatenates it with a random length. This approach is not as secure as the built-in `crypto.randomUUID()` method.
3. **Custom `generateID` function**: This function also generates a random string, but it uses a different character set and concatenation logic.

**Pros and Cons**

* **`crypto.randomUUID()`**:
	+ Pros: Highly secure, cryptographically strong, and widely supported.
	+ Cons: May be slower due to the overhead of cryptographic operations.
* **Custom `generateUUID` function**:
	+ Pros: More control over the generated string, potentially faster than `crypto.randomUUID()`.
	+ Cons: Less secure, as the character set is not designed for cryptographically strong randomness.
* **Custom `generateID` function**:
	+ Pros: Similar to the custom `generateUUID` function, with more control over the generated string.
	+ Cons: Even less secure than the custom `generateUUID` function.

**Library and Purpose**

The `crypto` module is a built-in JavaScript library that provides cryptographic functions, including the `randomUUID()` method. It is designed to generate cryptographically strong random numbers and UUIDs.

**Special JS Feature or Syntax**

There are no special JavaScript features or syntaxes used in this benchmark. The focus is on measuring the performance of generating random UUIDs using different approaches.

**Other Alternatives**

If you want to measure the performance of generating random strings, you can also consider using:

1. `Math.random()` with a large character set: This approach generates a random string by concatenating characters from a predefined set.
2. `String.fromCharCode()` and `Math.random()`: This approach uses the `String.fromCharCode()` function to generate a random ASCII code and then converts it to a character.

However, keep in mind that these alternatives may not be as secure or efficient as using the `crypto` module or implementing custom UUID generation functions specifically designed for this purpose.
