Benchmark: insertAdjacentHTML vs jquery.append_

HTML Preparation code:

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

Script Preparation code:


var str = "<div id='child'>child</div>";

Tests:

insertAdjacentHTML
var parent = document.getElementById('parent'); parent.insertAdjacentHTML('beforeend', str);
jquery.append
var parent = document.getElementById('parent'); $(parent).append(str);

Let's break down the provided JSON and explain what's being tested.

**Benchmark Definition**

The benchmark definition is about comparing two approaches: `insertAdjacentHTML` and `jquery.append`. The script preparation code inserts a string containing HTML into an existing element (`<div id='child'>child</div>`), while the HTML preparation code sets up the DOM with a parent element (`<div id="parent">parent</div>`) and includes jQuery library.

**Options Compared**

The two approaches being compared are:

1. `insertAdjacentHTML`: This method is a part of the DOM API, introduced in ECMAScript 2017 (ES7). It allows inserting HTML content before, after, or inside an element without modifying its existing structure.
2. `jquery.append`: This method is a part of the jQuery library, which provides a way to dynamically add elements to the DOM.

**Pros and Cons**

Here are some pros and cons of each approach:

* `insertAdjacentHTML`:
	+ Pros: Fast, efficient, and flexible. It allows inserting HTML content without modifying the original element's structure.
	+ Cons: Requires modern browsers that support ES7 syntax (e.g., Firefox 126).
* `jquery.append`: 
	+ Pros: Works in older browsers that don't support ES7 syntax, and jQuery provides a simple API for appending elements to the DOM.
	+ Cons: Can be slower than `insertAdjacentHTML` because it involves creating a new element and adding it to the DOM.

**Other Considerations**

When choosing between these approaches, consider the following:

* Browser compatibility: If you need to support older browsers that don't support ES7 syntax, `jquery.append` might be a better choice.
* Performance: If speed is critical, `insertAdjacentHTML` might be a better option due to its efficiency.
* Code readability and maintainability: `jquery.append` can make the code more readable if you're already familiar with jQuery.

**Library and Syntax**

The provided benchmark uses the jQuery library (`<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.js'></script>`). The syntax used is JavaScript, specifically ES7 (for `insertAdjacentHTML`).

**Special JS Features or Syntax**

There are no special JS features or syntax mentioned in the benchmark.

**Alternatives**

If you need to compare other approaches, here are some alternatives:

* Using `innerHTML` instead of `insertAdjacentHTML`
* Comparing with `appendChild` and `createElement` methods
* Testing `DOMSubtreeModificationException` (a more advanced approach)

Keep in mind that these alternative benchmarks would require significant changes to the script preparation code and benchmark definition.

I hope this explanation helps you understand what's being tested in the provided JSON!
