Benchmark: JQuery version speed test 3.1.1 vs 3.51

HTML Preparation code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
  var $jq311 = $.noConflict(true);
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
  var $jq351 = $.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:

$jq311
tests($jq311);
$jq351
tests($jq351);

**Benchmark Overview**

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks. The provided JSON represents a benchmark test case, which compares the performance of two versions of jQuery: 3.1.1 and 3.5.1.

**Tested Options**

The benchmark tests two options:

1. **jQuery version 3.1.1**: This is the older version of jQuery.
2. **jQuery version 3.5.1**: This is the newer version of jQuery, which introduces various performance improvements and bug fixes.

**Comparison**

The benchmark compares the execution speed of the two versions of jQuery by running a simple test case that creates a DOM structure using jQuery's API. The test case appends an element to the page using `$jq311` (for jQuery 3.1.1) or `$jq351` (for jQuery 3.5.1).

**Pros and Cons**

* **jQuery version 3.1.1**:
	+ Pros: This version of jQuery might be more compatible with older browsers or applications.
	+ Cons: It's an older version, which means it may not have the latest performance improvements or bug fixes.
* **jQuery version 3.5.1**:
	+ Pros: This version of jQuery has improved performance and bug fixes compared to 3.1.1, making it a better choice for modern web applications.
	+ Cons: It might be less compatible with older browsers or applications.

**Library and Purpose**

The `$.noConflict(true)` method is used in both test cases. This method returns the jQuery object wrapped in a function, allowing the code to run without conflicting with other libraries that use jQuery. The purpose of this method is to ensure that the test case works correctly even if there are other libraries using jQuery.

**Special JS Feature or Syntax**

There is no specific JavaScript feature or syntax used in this benchmark that requires special attention. However, it's worth noting that MeasureThat.net uses a custom scripting language for its benchmarks, which allows users to write simple scripts and run them on their servers.

**Other Alternatives**

If you're interested in running similar benchmarks, you can try the following alternatives:

1. **BenchmarkDotNet**: A popular benchmarking library for .NET languages.
2. **Google Benchmark**: An open-source benchmarking library developed by Google.
3. **JsPerf**: A JavaScript benchmarking tool that allows users to compare the performance of different JavaScript implementations.

Keep in mind that each of these alternatives has its own strengths and weaknesses, and you should choose the one that best fits your needs.
