Benchmark: jQuery 3.5 versus 1.11.0

HTML Preparation code:

<script src='https://code.jquery.com/jquery-1.12.4.min.js'></script>
<script>
  var $jq1124 = $.noConflict(true);
</script>
<script src="https://code.jquery.com/jquery-1.11.0.min.js"></script>
<script>
  var $jq1110 = $.noConflict(true);
</script>
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script>
  var $jq1113 = $.noConflict(true);
</script>
<script src="https://code.jquery.com/jquery-3.5.0.min.js"></script>
<script>
  var $jq35 = $.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' + $);
}

1.12.4
tests($jq1124);
1.11.0
tests($jq1110);
1.11.3

Let's break down the provided benchmark definition and individual test cases.

**Benchmark Definition**

The benchmark definition json represents a JavaScript microbenchmark that tests the performance of two versions of jQuery: 1.12.4, 1.11.0, 1.11.3, and 3.5.0. The script preparation code is a function named "tests" that takes a jQuery object ($) as an argument. Inside this function, it performs several operations:

* Finds the element with class ".menu-item" at index 2 in the DOM.
* Moves the closest "ul" element to its parent and sets its background color to red.
* Moves the parent of the previous step's result to a different position and sets its border to blue.
* Appends a new paragraph element to the previous step's result with some CSS styles.
* Removes all elements from the DOM.

The html preparation code includes multiple versions of jQuery loaded in different orders, which is used to test the browser's behavior when using different versions of jQuery.

**Individual Test Cases**

Each test case represents a separate benchmark that tests only one version of jQuery. The test name and benchmark definition are:

* "1.12.4": `tests($jq1124);`
* "1.11.0": `tests($jq1110);`
* "1.11.3": `tests($jq1113);`
* "3.5.0": `tests($jq35);`

Each test case only tests one version of jQuery and measures its performance.

**Library: jQuery**

jQuery is a popular JavaScript library that simplifies DOM manipulation, event handling, and Ajax interactions. In this benchmark, it's used to perform various DOM operations, such as finding elements, moving them around, and appending new content.

**Special JS Feature/ Syntax:** None mentioned

**Options Compared**

The benchmark compares the performance of four different versions of jQuery:

* 1.12.4 (older version)
* 1.11.0 (older version)
* 1.11.3 (medium age version)
* 3.5.0 (latest version)

By testing these different versions, we can see how the browser's performance changes as it uses more recent versions of jQuery.

**Pros and Cons**

Using multiple versions of jQuery has both advantages and disadvantages:

Advantages:

* Allows us to test the browser's behavior when using different versions of jQuery.
* Helps us identify which version is most performant in terms of execution speed.

Disadvantages:

* Can be complex to manage and maintain, especially if we have many versions.
* May lead to inconsistencies or bugs due to differences between versions.

**Other Alternatives**

If you want to create similar benchmarks for other JavaScript libraries or features, consider the following options:

* Use a different library, such as Lodash or Underscore.js, to test its performance.
* Test specific JavaScript features, like async/await or promises, using a benchmarking framework.
* Create benchmarks for other browsers or platforms, like Edge or Safari.

Keep in mind that benchmarking is an essential part of software engineering, and it helps us identify performance bottlenecks and optimize our code for better execution speed.
