Benchmark: dataset vs getAttribute() vs jQuery.data() vs jQuery.attr()

HTML Preparation code:

<h3 id="data" data-test="text">Some test content</h3>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js" integrity="sha512-bLT0Qm9VnAYZDflyKcBaQ2gg0hSYNQrJ8RilYldYQ1FxQYoCLtUjuuRuZo+fjqhx/qtq/1itJ0C2ejDxltZVFg==" crossorigin="anonymous"></script>

Tests:

dataset
window.onload = function() { var test = document.querySelector("h3#data").dataset.test; document.querySelector("h3#data").dataset.test = test+"1"; }
getAttribute
window.onload = function() { var test = document.querySelector("h3#data").getAttribute("test"); document.querySelector("h3#data").setAttribute("test", test+"1"); }
jQuery .data()
$(document).ready(function() { var $h3 = $("h3#data"); var test = $h3.data("test"); $h3.data("test", test+"1"); });
jQuery .attr()
$(document).ready(function() { var $h3 = $("h3#data"); var test = $h3.attr("data-test"); $h3.attr("data-test", test+"1"); });

**Benchmark Overview**

The MeasureThat.net benchmark compares the performance of three approaches to update and retrieve data attribute values in HTML elements: `dataset`, `getAttribute()`, `jQuery.data()`, and `jQuery.attr()`.

**Test Cases**

Each test case is designed to measure the execution time of a specific approach:

1. **`dataset`**: Retrieves and updates the value of a dataset attribute using the dot notation (`test.dataset.test`) and assignment (`test.dataset.test = test + "1"`).
2. **`getAttribute()`**: Uses the `getAttribute()` method to retrieve and update the value of an attribute with the specified name (`"test"`).
3. **`jQuery.data()`**: Utilizes jQuery's `.data()` method to store and retrieve data associated with an element, using a key-value pair (`"test"`, `"value"`).
4. **`jQuery.attr()`**: Employs jQuery's `.attr()` method to access and modify attribute values.

**Comparison Options**

The benchmark compares the performance of each approach across different browsers (Chrome 127) on desktop devices running Windows operating systems.

**Pros and Cons**

1. **`dataset`**:
	* Pros: Simple, native JavaScript implementation; fast execution times.
	* Cons: May not work in older browsers or those with broken DOM implementations.
2. **`getAttribute()`**:
	* Pros: Widely supported across modern browsers; can be used for attribute manipulation.
	* Cons: Slower execution times compared to `dataset`.
3. **`jQuery.data()`**:
	* Pros: Convenient, feature-rich API; well-supported in jQuery version 1.4 and later.
	* Cons: Requires jQuery library inclusion; slower execution times compared to `dataset`.
4. **`jQuery.attr()`**:
	* Pros: Fast execution times; convenient API for attribute manipulation.
	* Cons: Requires jQuery library inclusion.

**Library and Syntax**

The benchmark uses the jQuery library (version 3.5.1) to utilize `.data()` and `.attr()` methods.

There are no special JavaScript features or syntax used in this benchmark that would require advanced knowledge of JavaScript to understand.

**Other Alternatives**

If you need an alternative approach, consider:

* **`DOMTokenList`**: A modern API for working with HTML attributes. It's faster than `getAttribute()` and `attr()`, but might not be supported in older browsers.
* **`MutationObserver`**: An API for observing changes to the DOM. It can be used to detect attribute changes, but its performance characteristics depend on browser support.

Keep in mind that these alternatives may require additional setup or library inclusion.
