Benchmark: Testing append - MeasureThat.net

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.js'></script>
<ul id="lala">
</ul>

Tests:

JS
var el = document.getElementById('lala'); var txt = '' for(x=0; x<100; x++){ txt += "<li>Llala </li>"; } el.innerHTML = txt;
JQUERY
var el = $("#lala"); $.each(new Array(3), function(e){ el.append("<li>Llala </li>"); });

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

**Benchmark Definition:**

The provided JSON represents a JavaScript microbenchmark that tests two approaches:

1. **Native JavaScript**: The first approach uses native JavaScript to create an HTML list (`<ul>`) and append 100 `<li>` elements to it.
2. **jQuery**: The second approach uses jQuery to achieve the same result.

**Options compared:**

The benchmark compares the performance of these two approaches on a desktop platform using Chrome 87 browser and Mac OS X 11.0.1 operating system.

**Pros and Cons of each approach:**

**Native JavaScript:**

Pros:

* Native execution, likely optimized for performance
* No dependency on external libraries
* Simple and straightforward code

Cons:

* May require more manual DOM manipulation and string concatenation
* Might be slower due to the overhead of creating and updating the HTML list

**jQuery:**

Pros:

* Faster execution due to jQuery's optimization and caching mechanisms
* Simplifies DOM manipulation with its API
* Easier to read and maintain code

Cons:

* Adds an external dependency (jQuery library)
* May introduce additional overhead due to parsing and executing the JavaScript code

**Library Used:**

In this benchmark, jQuery is used as a library to simplify the DOM manipulation. The `$(\"#lala\")` syntax is used to select the HTML element with the id "lala", and the `append()` method is used to add elements to the list.

**Special JS Feature/Syntax:**

None of the test cases use special JavaScript features or syntax that would require additional explanation. Both approaches are relatively simple and straightforward.

**Other Alternatives:**

If you want to create a similar benchmark, you could consider adding more test cases with different libraries, DOM manipulation techniques, or even native WebAssembly code. Some alternative approaches could include:

* Using vanilla JavaScript's `String.prototype.repeat()` method instead of string concatenation
* Utilizing a library like React or Angular for building the UI
* Implementing the benchmark using WebAssembly (WASM) and comparing its performance to native JavaScript
* Adding test cases with different browser versions, operating systems, or device platforms

Keep in mind that creating a comprehensive benchmark requires careful consideration of various factors, including code complexity, optimization techniques, and execution environment.
