Benchmark: .attribute vs setAttribute/removeAttribute vs setAttributeNode/removeAttributeNode vs attributes.setNamedItem/attributes.removeNamedITem

HTML Preparation code:

<div id="testNode"></div>

Script Preparation code:

var testElement = document.getElementById("testNode");
var hiddenAttr = document.createAttribute("hidden");

Tests:

.attribute
testElement.hidden = true; testElement.hidden = false;
setAttribute/removeAttribute
testElement.setAttribute("hidden", ""); testElement.removeAttribute("hidden");
setAttributeNode/removeAttributeNode
testElement.setAttributeNode(hiddenAttr); testElement.removeAttributeNode(hiddenAttr);
attributes.setNamedItem/attributes.removeNamedITem
testElement.attributes.setNamedItem(hiddenAttr); testElement.attributes.removeNamedItem("hidden");

Let's dive into the world of JavaScript microbenchmarks.

**Benchmark Overview**

The provided benchmark compares four different approaches to set and remove an attribute from an HTML element:

1. Using the `.attribute` syntax (e.g., `testElement.hidden = true;`)
2. Using the `setAttribute` method with a string argument (e.g., `testElement.setAttribute("hidden", "");`)
3. Using the `setAttributeNode` method with a DOMAttr object as an argument (e.g., `testElement.setAttributeNode(hiddenAttr);`)
4. Using the `attributes.setNamedItem` method with a DOMString as an argument (e.g., `testElement.attributes.setNamedItem(hiddenAttr);`)

**Options Comparison**

Here's a brief overview of each approach, including their pros and cons:

1. **.attribute syntax**
	* Pros: Easy to read and write, doesn't require explicit string concatenation or attribute creation.
	* Cons: May be slower due to the JavaScript engine's interpretation of the syntax.
2. **setAttribute/removeAttribute**
	* Pros: Fast and efficient, as it involves a direct call to the DOM API.
	* Cons: Requires explicit string manipulation, which can lead to errors if not done correctly.
3. **setAttributeNode/removeAttributeNode**
	* Pros: Similar to `setAttribute`/`removeAttribute`, but with more control over attribute creation and modification.
	* Cons: May require more boilerplate code, especially for complex attributes.
4. **attributes.setNamedItem/attributes.removeNamedItem**
	* Pros: Provides a more explicit and controlled way of working with attributes, similar to `setAttributeNode`.
	* Cons: Requires knowledge of the DOM Attributes API and may be slower due to additional overhead.

**Library Considerations**

In this benchmark, none of the test cases use any external libraries. The code is self-contained and only relies on the standard JavaScript DOM API.

**Special JS Features/Syntax**

None of the test cases explicitly use special JavaScript features or syntax beyond what's typically used in web development (e.g., ES6+ syntax). However, it's worth noting that some of these approaches may rely on specific browser implementations or engine optimizations, which could affect their performance.

**Other Alternatives**

If you're interested in exploring other alternatives for working with attributes in JavaScript, consider the following:

* **DOM Attributes API**: Provides a more explicit and controlled way of working with attributes, similar to `setAttributeNode`/`removeAttributeNode`.
* **JS APIs like jQuery**: Can simplify attribute manipulation, but may introduce additional overhead or dependencies.
* **Library-specific solutions**: Some libraries (e.g., React, Angular) provide their own solutions for handling attributes, which might be worth exploring if you're already invested in those ecosystems.

Keep in mind that this benchmark focuses on comparing the performance of different approaches within a specific JavaScript context. Depending on your use case and requirements, other alternatives may be more suitable.
