Benchmark: JQuery: test selector with three redundant type

HTML Preparation code:

<form id="userForm">
  <input type="text" name="name"/>
  <input type="password" name="password"/>
  <input type="checkbox" name="isHaveExperience" value="true"/>
  <input type="radio" name="difficult" value="easy"/>
  <input type="radio" name="difficult" value="medium"/>
  <input type="radio" name="difficult" value="hard"/>
</form>
<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.js'></script>

Script Preparation code:

var $userFormElement = $("#userForm");

Tests:

using not equal attribute
let $searchElements = $userFormElement.find("[type!=password][type!=checkbox][type!=radio]");
using :not selector
let $searchElements = $userFormElement.find(":not([type=password]):not([type=checkbox]):not([type=radio])");

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

**Benchmark Overview**

The benchmark is designed to measure the performance of jQuery's selector engine on finding elements that do not match three specific input types (password, checkbox, or radio). The goal is to determine which approach is faster: using a "not equal" attribute in the selector or using the `:not` pseudo-class.

**Script Preparation Code**

The script preparation code creates a `$userFormElement` variable by selecting an HTML form element with the ID `userForm`. This variable will be used as a context for the selection.

**Html Preparation Code**

The HTML preparation code defines an HTML form with several input elements, including:

* Three text inputs (name, password, and isHaveExperience)
* Two radio buttons (difficult) with different values

This setup allows us to test the selector engine on finding elements that do not match any of the three specified input types.

**Individual Test Cases**

There are two test cases:

1. **"using not equal attribute"`**
The first test case uses the "not equal" attribute in the selector: `$userFormElement.find("[type!=password][type!=checkbox][type!=radio]");`. This approach directly specifies the allowed input types using an attribute.
2. **"using :not selector"`**
The second test case uses the `:not` pseudo-class in the selector: `$userFormElement.find(":not([type=password]):not([type=checkbox]):not([type=radio])");`. This approach uses a different syntax to specify the excluded input types.

**Library and Purpose**

In this benchmark, jQuery is used as a library. Its purpose is to provide a robust and efficient way to select elements on an HTML document. In this case, it's used to find elements that match specific conditions (in or not in certain input types).

**Special JS Feature or Syntax**

This benchmark uses the `:not` pseudo-class, which is a feature introduced in jQuery 1.9. The syntax is different from other CSS selectors and requires a good understanding of how it works.

**Pros and Cons**

Here are some pros and cons for each approach:

* **"using not equal attribute"`**
Pros:
	+ Easy to read and understand
	+ Directly specifies allowed input types
Cons:
	+ May lead to slower performance due to the extra step of filtering out unwanted types
* **"using :not selector"`**
Pros:
	+ More concise and efficient than using "not equal" attributes
	+ Can be faster because it directly filters out unwanted elements
Cons:
	+ Requires a good understanding of how `:not` works with CSS selectors

**Other Alternatives**

There are other alternatives to approach this benchmark:

* **CSS Filters**: Instead of using jQuery's selector engine, you could use the browser's built-in CSS filter capabilities to achieve the same result.
* **Regular Expressions**: Another approach would be to use regular expressions to match the desired input types. However, this might lead to slower performance due to the complexity of matching patterns.

Overall, both approaches have their pros and cons, and the best choice depends on the specific requirements and constraints of your project.
