Benchmark: Jquery Vs VanillaJS + specifying ID/class with count

HTML Preparation code:

<script src='https://code.jquery.com/jquery-3.6.0.min.js'></script>

<div id='test' data-count="0"></div>

Tests:

Jquery
$('#test').data('count', 0); for(let i = 0; i < 10; i++) { $('#test').text("actual count value is : "+$('#test').data('count')); $('#test').data('count', +$('#test').data('count')+1); }
Vanilla JS
document.querySelector('#test').dataset.count = 0; for(let i = 0; i < 10; i++) { document.querySelector('#test').innerText = "actual count value is : "+document.querySelector('#test').dataset.count; document.querySelector('#test').dataset.count = +document.querySelector('#test').dataset.count+1; }
Vanilla JS specifying ID/class
document.getElementById('test').dataset.count = 0; for(let i = 0; i < 10; i++) { document.getElementById('test').innerText = "actual count value is : "+document.getElementById('test').dataset.count; document.getElementById('test').dataset.count++; }

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

**Benchmark Overview**

The benchmark compares three approaches for updating a DOM element's dataset (also known as attributes) in JavaScript:

1. jQuery (`Jquery` test case)
2. Vanilla JavaScript with `dataset` property (`Vanilla JS` test case)
3. Vanilla JavaScript using `getElementById` and incrementing the `dataset.count` attribute value manually (`Vanilla JS specifying ID/class` test case)

**Options Compared**

The benchmark is comparing the performance of these three approaches:

* jQuery's `$()` function, which updates the dataset property directly.
* Vanilla JavaScript's `document.querySelector()` method with `dataset` property access, which requires an additional lookup to retrieve the element by its selector.
* Vanilla JavaScript's `document.getElementById()` method, which retrieves the element by its ID and then accesses the `dataset.count` attribute value manually.

**Pros and Cons of Each Approach**

1. **jQuery (`Jquery`)**: Pros:
	* Fast and efficient, as jQuery is optimized for DOM manipulation.
	* Easy to use, especially for developers familiar with jQuery's API.
Cons:
	* Requires an additional HTTP request to load the jQuery library, which may impact performance in some cases.
2. **Vanilla JavaScript with `dataset` property (`Vanilla JS`)**: Pros:
	* Faster than using `document.querySelector()` and accessing the `dataset` property manually.
	* More modern and efficient approach, as it uses a standardized API for accessing attribute values.
Cons:
	* Requires a single HTTP request to load the browser's default JavaScript library (e.g., V8 in Chrome).
3. **Vanilla JavaScript using `getElementById` and incrementing (`Vanilla JS specifying ID/class`)**: Pros:
	* Only requires a single HTTP request, as it uses the built-in `document.getElementById()` method.
Cons:
	* Slower than the other two approaches, due to the additional lookup required to retrieve the element by its ID.

**Library Purpose**

In the jQuery test case, the library is used for DOM manipulation and attribute updates. The `$()` function is used to select the DOM element (`#test`), update its dataset property, and repeat this process 10 times.

In the Vanilla JS test cases, the `dataset` property is accessed directly on the selected element to retrieve or update its attribute value.

**Special JS Feature/Syntax**

The benchmark uses modern JavaScript features, such as:

* Template literals (`"actual count value is : \"+$('#test').data('count')"` in jQuery and `"actual count value is : "+document.querySelector('#test').dataset.count;"` in Vanilla JS)
* Arrow functions (e.g., `() => { ... }`)
* Optional chaining (e.g., `$('#test').data('count', 0) ?? null;`)

These features are supported by modern browsers, including the ones used to run the benchmark.

**Other Alternatives**

If you need to update a DOM element's attribute value in JavaScript, other alternatives include:

* Using `setAttribute()` and `getAttribute()` methods
* Using a library like React or Angular for more complex DOM updates
* Using a framework like jQuery itself (although this is already included in the benchmark)

Keep in mind that each approach has its trade-offs and performance implications.
