Benchmark: json stringify urlsafe vs array tostring base64

Script Preparation code:

function moreData(arr, left) {
  if(left === 0) return arr;
  else {
    arr.push(Math.floor(Math.random() * 256));
  	return moreData(arr, left - 1);
  }
}
function makeTestData() { return moreData([], 4); }

Tests:

to base64 string
makeTestData().toString("base64")
json stringify
encodeURIComponent(JSON.stringify(makeTestData()));

Let's break down the benchmark and explain what's being tested, compared, and other considerations.

**Benchmark Overview**

The benchmark is designed to compare two approaches for encoding data in JavaScript:

1. **URL-safe base64 string**: This approach uses the `base64` function to encode the data.
2. **JSON.stringify with encodeURIComponent**: This approach uses the `encodeURIComponent` function to convert the encoded data into a URL-safe format.

**Script Preparation Code**

The script preparation code generates test data by recursively pushing random numbers onto an array, starting from index 0, and then converts this array to a base64 string using the `makeTestData()` function. The generated test data is then used to create two benchmark definitions: one for encoding the data as a URL-safe base64 string, and another for encoding it using JSON.stringify with encodeURIComponent.

**Library**

The `base64` function is not explicitly mentioned in the code, but it's likely that this is an external library or built-in function. In modern JavaScript, the `btoa()` (binary to ASCII) function can be used to achieve similar results.

**Special JS Feature/Syntax**

There are no special JavaScript features or syntax used in this benchmark, apart from the use of `JSON.stringify`, which is a standard JavaScript method for converting objects into strings.

**Comparison Options**

The two comparison options are:

1. **URL-safe base64 string**
	* Pros:
		+ Faster execution times (as seen in the latest benchmark results)
		+ More efficient data encoding
	* Cons:
		+ May not be as widely supported or compatible across different browsers and systems
2. **JSON.stringify with encodeURIComponent**
	* Pros:
		+ Widely supported and compatible across different browsers and systems
		+ Easier to implement and understand for developers familiar with JSON and URL encoding
	* Cons:
		+ Slower execution times (as seen in the latest benchmark results)
		+ May result in larger encoded data sizes

**Other Considerations**

When choosing between these two approaches, consider the following factors:

1. **Performance**: If speed is critical, using a base64 function may be the better choice.
2. **Compatibility**: If you need to support older browsers or systems with limited compatibility, JSON.stringify with encodeURIComponent might be a safer bet.
3. **Data Size**: If smaller data sizes are important, encoding data using JSON.stringify with encodeURIComponent might be more suitable.

**Other Alternatives**

If you're interested in exploring other alternatives, here are a few options:

1. **Buffer API**: You can use the `Buffer` class to encode and decode binary data.
2. **TextEncoder/Decoder API**: These APIs provide a more efficient way to work with text data encoding and decoding.
3. **Custom encoding algorithms**: Depending on your specific requirements, you might need to implement a custom encoding algorithm that suits your needs.

Keep in mind that each of these alternatives has its own trade-offs and considerations, so be sure to evaluate them carefully before making a decision.
