Benchmark: Shorthand set/getAttribute vs native

HTML Preparation code:

<div id="test-subject" data-test="foo"></div>

Tests:

Shorthand
function attr(element, attribute, value) { if (value) { element.setAttribute(attribute, value); return; } return element.getAttribute(attribute); } var test_subject = document.getElementById("test-subject"); var i = 1000; while (i--) { attr(test_subject, 'data-test', i); test_subject.innerHTML = attr(test_subject, 'data-test'); }
Native
var test_subject = document.getElementById("test-subject"); var i = 1000; while (i--) { test_subject.setAttribute('data-test', i); test_subject.innerHTML = test_subject.getAttribute('data-test'); }

I'll break down the provided benchmark and explain what's being tested, compared, and their pros and cons.

**Benchmark Overview**

The MeasureThat.net benchmark compares two approaches to setting/getting attributes on an HTML element: a "shorthand" method using JavaScript's `setAttribute` and `getAttribute` methods in a single call, versus the native way of setting/getting attributes using separate calls for each operation.

**Shorthand Method (Test Name: Shorthand)**

The shorthand method is defined as follows:
```javascript
function attr(element, attribute, value) {
    if (value) {
        element.setAttribute(attribute, value);
        return;
    }
    return element.getAttribute(attribute);
}

var test_subject = document.getElementById("test-subject");
var i = 1000;
while (i--) {
    attr(test_subject, 'data-test', i);
    test_subject.innerHTML = attr(test_subject, 'data-test');
}
```
**Native Method (Test Name: Native)**

The native method is defined as follows:
```javascript
var test_subject = document.getElementById("test-subject");
var i = 1000;
while (i--) {
    test_subject.setAttribute('data-test', i);
    test_subject.innerHTML = test_subject.getAttribute('data-test');
}
```
**Comparison**

Both methods are executed in a loop, with the `attr` function being called with different values for the `attribute` and `value` parameters. The native method uses separate calls for setting (`setAttribute`) and getting (`getAttribute`), while the shorthand method combines both operations into a single call.

**Pros and Cons of Each Approach**

* **Shorthand Method:**
	+ Pros:
		- Potential performance improvement due to reduced function call overhead.
		- Simplified code by eliminating the need for separate `setAttribute` and `getAttribute` calls.
	+ Cons:
		- May introduce additional overhead due to the complexity of the `attr` function.
		- Might lead to decreased readability and maintainability of the code.
* **Native Method:**
	+ Pros:
		- Clear and concise code that is easy to understand and maintain.
		- Avoids potential performance issues introduced by the shorthand method's combined calls.
	+ Cons:
		- May result in slightly higher function call overhead due to separate `setAttribute` and `getAttribute` calls.

**Library Usage**

The benchmark uses the built-in JavaScript `document.getElementById()` and `HTMLElement.setAttribute()`/`HTMLElement.getAttribute()` methods, which are part of the standard DOM API. These methods are widely supported across different browsers and platforms.

**Special JS Features or Syntax**

This benchmark does not use any special JavaScript features or syntax that would require specific browser support or configuration.

**Alternative Approaches**

Other approaches to setting/getting attributes on an HTML element might include:

* Using a library like jQuery, which provides a simplified API for manipulating the DOM.
* Implementing custom attribute management logic using a separate utility function or class.
* Using Web Workers or other parallel execution techniques to optimize performance.
* Employing different serialization formats (e.g., JSON) for storing and retrieving attributes.

However, these alternatives are not being tested in this specific benchmark.
