Benchmark: JQuery 1.7 VS 3.3.1

HTML Preparation code:

<script src='https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js'></script>
<script>
  var $jq172 = $.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>
<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' + $);
}

Let's break down the provided benchmark definition and test cases to understand what is being tested.

**Benchmark Definition**

The benchmark is comparing the performance of two versions of jQuery: 1.7.2 and 3.3.1. The script preparation code contains two functions, `tests($jq172)` and `tests($jq331)`, which are executed with different versions of jQuery. The `$.noConflict(true)` method is used to avoid conflicts between the two versions.

**Html Preparation Code**

The HTML preparation code includes:

* Two `<script>` tags loading jQuery 1.7.2 and 3.3.1 respectively
* A `<div>` element containing an unordered list (`<ul>`) with four list items (`<li>`)
* JavaScript code that selects the second list item, applies styles to its parent, and appends a new paragraph element

**Individual Test Cases**

There are two test cases:

* `$jq172`: Tests jQuery 1.7.2
* `$jq331`: Tests jQuery 3.3.1

**Comparison Options**

The benchmark is comparing the performance of these two jQuery versions in the following aspects:

1. ** DOM Manipulation**: The script preparation code contains DOM manipulation operations, such as appending a new paragraph element and changing styles.
2. **Browser Compatibility**: The use of `$.noConflict(true)` method suggests that the benchmark is checking for browser compatibility issues between the two jQuery versions.

**Pros and Cons**

Here are some pros and cons of using these approaches:

* Using multiple versions of jQuery can help identify performance differences, but it may also introduce additional complexity and potential compatibility issues.
* The use of `$.noConflict(true)` method can be beneficial in avoiding conflicts between different versions of jQuery, but it may also add overhead to the benchmark.

**Library and Purpose**

The jQuery library is a popular JavaScript library used for DOM manipulation and event handling. It provides a set of functions that simplify web development tasks, such as selecting elements, animating them, and handling events.

In this benchmark, jQuery 1.7.2 and 3.3.1 are being compared to determine which version performs better in terms of execution speed and browser compatibility.

**Special JS Features or Syntax**

None mentioned explicitly, but the use of `$.noConflict(true)` method suggests that the benchmark is aware of potential conflicts between different versions of jQuery.

**Other Alternatives**

If you're interested in running a similar benchmark, here are some alternatives:

* You can use a testing framework like Jest or Mocha to create and run your own benchmarks.
* You can use a browser-specific benchmarking library like Blink or SpiderMonkey to compare the performance of different JavaScript engines.
* You can also use online platforms like BenchmarkJS or JSPerf to create and run benchmarks.

Keep in mind that each alternative has its own strengths and weaknesses, and the best approach will depend on your specific needs and goals.
