Benchmark: Vanilla JS VS JQuery DOM add/remove class performance

HTML Preparation code:

<script src="//ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<div id="nhngodo">Hi! NHNgodo!</div>

Tests:

Vanilla JS add class
let el = document.getElementById("nhngodo"); el.classList.add('random-class'); el.classList.remove('random-class');
Jquery
let $el = $("#nhngodo"); $el.addClass('random-class'); $el.removeClass('random-class');

**Overview of the Benchmark**

The provided JSON represents a JavaScript microbenchmarking test case on MeasureThat.net. The test measures the performance difference between using vanilla JavaScript and jQuery to add and remove classes from an HTML element.

**What is being tested?**

Two specific options are being compared:

1. **Vanilla JS**: Using native JavaScript methods to add and remove classes from an element.
2. **JQuery**: Using jQuery's `addClass` and `removeClass` methods to achieve the same functionality.

**Pros and Cons of each approach:**

* **Vanilla JS**:
	+ Pros:
		- Lightweight, no additional library dependency.
		- More control over execution order and optimizations.
	+ Cons:
		- May require more code and manual management of class names.
		- Can be slower due to the overhead of `document.querySelector` and `classList` manipulation.
* **JQuery**:
	+ Pros:
		- Simplifies class management with a single, concise API.
		- Optimizations and caching are handled by jQuery.
	+ Cons:
		- Adds an additional library dependency, which may impact page load times.
		- May introduce overhead due to the jQuery framework's complexity.

**Library: jQuery**

jQuery is a popular JavaScript library that simplifies DOM manipulation and event handling. In this benchmark, it is used to add and remove classes from an element using its `addClass` and `removeClass` methods. jQuery provides a convenient API for class management, which can simplify code and improve performance by leveraging optimizations and caching.

**Special JS feature: None**

There are no special JavaScript features or syntaxes mentioned in the benchmark definition or test cases.

**Alternatives to vanilla JS and jQuery:**

For this specific use case, other alternatives could be:

1. **React**: A popular front-end library for building reusable UI components. While it's not primarily designed for class management, React can simplify DOM updates using its `className` prop.
2. **Lodash**: A utility library that provides a concise API for class manipulation and other common tasks.
3. **Preact**: Another lightweight JavaScript framework that aims to provide a balance between React and vanilla JS.

However, for this specific benchmark, the focus is on comparing vanilla JS and jQuery implementations, making these alternatives less relevant.
