Benchmark: URL vs URLSearchParams vs RegExp

Script Preparation code:

var location_href = "https://www.youtube.com/watch?v=x2rvSf0STBM&list=RDCLAK5uy_kvhjcPWzH7xZL-WnqGbiA_euQGy5_cbHI&start_radio=1";
var location_search = "?v=x2rvSf0STBM&list=RDCLAK5uy_kvhjcPWzH7xZL-WnqGbiA_euQGy5_cbHI&start_radio=1";
var loop = 10000;
var loop_n = 3000;
var urls = new Array(loop_n).fill(0).map(()=>{
  let t = Math.round(Math.random()*80000+10000);
  return {
    href: `${location_href}${t}`,
    search: `${location_search}${t}`
  };
})

Tests:

URL
for(let i=loop_n;--i;){ new URL(urls[i].href).searchParams.has("list"); }
URLSearchParams
for(let i=loop_n;--i;){ new URLSearchParams(urls[i].search).has("list"); }
RegExp1
for(let i=loop_n;--i;){ /https\:\/\/www\.youtube\.com\/watch.*[\?\&]list=[\w\-\_]+/.test(urls[i].href) }

**Overview**

The provided benchmark compares three approaches to test if the value 'list' exists in a URL string: `new URL()` with `searchParams.has()`, `new URLSearchParams()` with `has()`, and a regular expression (`RegExp1`) that matches URLs with the 'list' parameter.

**Test Cases**

* **URL**: Creates a new `URL` object from the provided `href` attribute, which contains the URL string. Then, uses the `searchParams.has()` method to check if the value 'list' exists in the URL's search parameters.
* **URLSearchParams**: Creates a new `URLSearchParams` object from the provided `search` attribute, which contains the URL string. Then, uses the `has()` method to check if the value 'list' exists in the URL's search parameters.
* **RegExp1**: Uses a regular expression (`/https:\/\/www\.youtube\.com\/watch.*[\\?\\&]list=[\\w\\-\\_]+/`) to match URLs with the 'list' parameter.

**Options Compared**

The benchmark compares the performance of each approach:

1. `new URL()` with `searchParams.has()`
2. `new URLSearchParams()` with `has()`
3. Regular expression (`RegExp1`) that matches URLs with the 'list' parameter

**Pros and Cons of Each Approach**

* **`new URL()` with `searchParams.has()`**:
	+ Pros: Easy to use, efficient, and widely supported.
	+ Cons: May not work correctly for all URL formats, can be slower than other approaches.
* **`new URLSearchParams()` with `has()`**:
	+ Pros: More efficient than using a regular expression, works well for most URL formats.
	+ Cons: Can be slower than the `URL` approach for certain use cases.
* **Regular Expression (`RegExp1`)**
	+ Pros: Highly customizable and can handle complex URL formats, but may be slower due to the overhead of regular expressions.

**Library Usage**

* None in this benchmark, as all three approaches rely on built-in JavaScript methods or regular expressions.

**Special JS Features or Syntax**

None mentioned in the provided code.

**Other Alternatives**

If you need to perform similar tasks, consider using other libraries or tools:

1. `url-parse`: A lightweight library for parsing URLs.
2. `query-string-escape`: A library for encoding and decoding URL query strings.
3. `regex`: A built-in JavaScript function for working with regular expressions.

Keep in mind that these alternatives may offer more features, flexibility, or performance than the approaches compared in this benchmark.
