Benchmark: JQuery version speed test jQuery 3.4.1

HTML Preparation code:

<script src='https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js'></script>
<script>
  var $jq1120 = $.noConflict(true);
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
<script>
  var $jq224 = $.noConflict(true);
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
  var $jq331 = $.noConflict(true);
</script>
<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script>
  var $jq340 = $.noConflict(true);
</script>
<div>
  <ul id="menu">
    <li class="menu-item">1</li>
    <li class="menu-item">2</li>
    <li class="menu-item">3</li>
    <li class="menu-item">4</li>  
  </ul>
</div>

Script Preparation code:

function tests($) {
    $(".menu-item").eq(2).closest("ul").css({
      "background-color": "red"
    }).parent().css({
      "border": "1px solid blue"
    }).append($("<p></p>").text("Text.").css({
      "background-color": "green"
    })).end().end().remove();
  console.log('tests' + $);
}

tests($jq1120);
Test jQuery 2.2.4
tests($jq224);

The provided benchmark definition and test cases are designed to measure the performance of jQuery versions 3.4.1, 3.4.0, 2.2.4, 3.3.1, and 1.12.0 in different browsers.

**Benchmark Definition:**
The script preparation code `tests($jqX)` is a simple benchmark that tests the performance of each jQuery version by:

1. Selecting an element with class "menu-item" (index 2) within an unordered list (`<ul>`) and setting its background color to red.
2. Setting the border of its parent element to 1px solid blue.
3. Appending a new paragraph element to the end of the previous operation, with a green background color.
4. Removing all elements from the DOM using `end()`.

The benchmark also includes a console log statement to display the jQuery version used for each test.

**Html Preparation Code:**
The provided HTML code loads multiple versions of jQuery (1.12.4, 2.2.4, 3.3.1, and 3.4.1) in different `script` tags, along with a no-conflict wrapper function (`$.noConflict(true)`). The `var $jqX` variable is assigned to the loaded jQuery version.

**Individual Test Cases:**
Each test case uses one of the loaded jQuery versions (3.4.0, 2.2.4, 3.3.1, or 1.12.0) and calls the `tests($jqX)` function to execute the benchmark.

**Options Compared:**

* Each test case compares a different version of jQuery (3.4.0, 2.2.4, 3.3.1, or 1.12.0).
* Within each test case, there is no explicit comparison between versions; instead, the same version is used for all operations.

**Pros and Cons:**

* **Advantages:**
	+ Easy to understand and execute.
	+ Allows for quick testing of different jQuery versions.
	+ Reduces overhead by only loading a single version of jQuery per test case.
* **Disadvantages:**
	+ Does not account for variations in browser behavior or performance differences between versions.
	+ Assumes that the same version is optimal for all operations.

**Library and Purpose:**
The `$.noConflict(true)` function is used to disable jQuery's conflict handling mechanism, which helps prevent conflicts with other libraries that use jQuery. Its purpose is to allow multiple libraries to coexist without issues.

No special JavaScript features or syntax are being tested in this benchmark.

**Other Alternatives:**

* **Alternative approach:** Instead of using a single version of jQuery per test case, you could create a separate test case for each version and compare the performance across versions. This would require more setup and complexity but would provide a more accurate picture of the performance differences between versions.
* **Alternative use case:** You could modify the benchmark to include additional operations or variations in the HTML structure to better simulate real-world usage scenarios and capture more realistic performance characteristics.

I hope this explanation helps!
