Benchmark: jQuery remove vs hide

HTML Preparation code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<div id="test-element">
  <ul class="test-element__list">
    <li>First Item</li>
    <li>Second Item</li>
    <li>Third Item</li>
  </ul>
</div>

Tests:

remove
$('#test-element > .test-element__list').remove();
hide
$('#test-element > .test-element__list').hide();

Let's dive into the world of MeasureThat.net and explore what's being tested in this benchmark.

**What is being tested?**

The provided JSON represents two test cases, each measuring the performance difference between removing and hiding an HTML element using jQuery. The tests are designed to evaluate how long it takes for the browser to execute these two operations.

**Options compared:**

There are two options being compared:

1. `remove()`: This method removes the specified element from the DOM.
2. `hide()`: This method sets the visibility of the specified element to hidden.

**Pros and Cons:**

* **`remove()`**:
	+ Pros:
		- Removes the element from the DOM, which can be beneficial for memory management and garbage collection.
		- Can be faster in some cases since it doesn't require setting a new style property (e.g., `display: none`).
	+ Cons:
		- May cause layout recalculations or other visual effects if not done carefully.
		- Can lead to increased DOM node count, which can negatively impact performance.
* **`hide()`**:
	+ Pros:
		- Faster since it only sets a new style property (e.g., `display: none`).
		- Does not affect the DOM node count, making it more suitable for elements that need to be reused or have dynamic content.
	+ Cons:
		- Does not remove the element from the DOM, which can lead to memory leaks if not handled properly.

**Library and its purpose:**

The test uses jQuery, a popular JavaScript library for simplifying DOM manipulation and event handling. In this context, jQuery provides an easy-to-use interface for removing and hiding elements, making it easier to focus on performance optimization rather than tedious manual DOM manipulation code.

**Special JS feature or syntax (None)**

This benchmark does not rely on any special JavaScript features or syntax beyond standard ECMAScript 2022 (ES12).

**Other alternatives:**

While jQuery is a widely used library for DOM manipulation, there are alternative approaches:

* **Vanilla JavaScript**: Using native JavaScript methods like `document.getElementById().style.display = 'none';` or `document.getElementById().remove();` instead of jQuery's methods.
* **Modern libraries**: Other popular libraries like React, Angular, or Vue.js might be used in different contexts to achieve similar performance benchmarks.

In the context of MeasureThat.net, it's essential to note that the benchmark results are likely optimized for jQuery usage and may not accurately represent the performance differences between using vanilla JavaScript or other libraries.
