Benchmark: JQuery version speed test jQuery 3.4.1 all 1

HTML Preparation code:

<script src='https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js'></script>
<script>
  var $jq1110 = $.noConflict(true);
</script>
<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/3.7.0/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:

Test jQuery 1.12.0
tests($jq1120);
Test jQuery 2.2.4
tests($jq224);
Test jQuery 3.3.1
tests($jq331);
Test jQuery 3.4.0

Let's dive into the details of this benchmark.

**Overview**

MeasureThat.net is a platform for JavaScript microbenchmarks, allowing users to create and run small benchmarks to compare the performance of different versions of jQuery. The provided benchmark definition includes:

1. A JSON object representing the benchmark definition, which contains information about the test case.
2. Individual test cases in an array format, each with its own Benchmark Definition and Test Name.

**Benchmark Definition**

The Benchmark Definition JSON object contains the following information:

* `Name`: The name of the benchmark, which is "JQuery version speed test jQuery 3.4.1 all 1".
* `Description`: A brief description of the benchmark.
* `Script Preparation Code`: A JavaScript function named `tests` that takes a `$` parameter, which represents the jQuery object.
* `Html Preparation Code`: The HTML code used to prepare the environment for the test.

The script preparation code is interesting because it:

1. Uses different versions of jQuery (1.11.3, 1.12.4, 2.2.4, 3.7.0) and creates separate instances using `$.noConflict(true)`.
2. Prepares a DOM element with an unordered list (`<ul>`) containing four menu items (`<li>`) with different classes.
3. Applies CSS styles to the elements using jQuery's `css()` method.

The script preparation code is executed in a specific order, and each subsequent test case uses a previously created instance of jQuery.

**Individual Test Cases**

Each individual test case has its own Benchmark Definition and Test Name:

1. "Test jQuery 1.12.0" (uses $jq1120)
2. "Test jQuery 2.2.4" (uses $jq224)
3. "Test jQuery 3.3.1" (uses $jq331)
4. "Test jQuery 3.4.0" (uses $jq340)
5. "Test jQuery 1.11.0" (uses $jq1110)

Each test case runs the `tests` function with its corresponding instance of jQuery, and measures the performance of the script.

**Library: jQuery**

jQuery is a popular JavaScript library for DOM manipulation and event handling. In this benchmark, jQuery is used to:

* Manipulate the DOM elements
* Apply CSS styles
* Execute scripts

The use of `$.noConflict(true)` creates separate instances of jQuery, allowing each test case to run with its own instance.

**Special JS Features/Syntax**

None are mentioned in this specific benchmark. However, some notes on related features:

* jQuery's `.css()` method is used extensively in the script preparation code.
* The use of `$.noConflict(true)` creates separate instances of jQuery, which can be useful for isolating tests or ensuring compatibility with older browsers.

**Other Alternatives**

If you wanted to recreate this benchmark, you could consider using alternative libraries or approaches:

1. Vanilla JavaScript: Instead of using jQuery, you could implement similar functionality using pure JavaScript.
2. Other DOM manipulation libraries (e.g., React, Angular): These libraries provide their own set of APIs for manipulating the DOM and executing scripts.
3. Browser-specific APIs: Some browsers provide native APIs for accessing the DOM and executing scripts (e.g., WebKit's `webkitAnimation` API).

Keep in mind that recreating this benchmark would likely require significant changes to the script preparation code, as well as potentially rewriting the test cases themselves.
