Benchmark: text vs comment2

Tests:

text
const node = document.body.appendChild(document.createTextNode('')); Promise.resolve().then(()=>document.body.removeChild(node));
comment
const node = document.body.appendChild(document.createComment('')); Promise.resolve().then(()=>document.body.removeChild(node));

**What is being tested?**

The benchmark tests the performance difference between two approaches:

1. **Appending a text node**: The script appends an empty string to the document body and then removes it using `document.body.removeChild`.
2. **Appending a comment node**: The script appends an empty comment to the document body and then removes it using `document.body.removeChild`.

**Options compared**

The two options being compared are:

* Appending a text node (`document.createTextNode('')`)
* Appending a comment node (`document.createComment('')`)

**Pros and Cons of each approach:**

1. **Appending a text node**:
	* Pros:
		+ More control over the DOM tree structure, which can lead to better performance in certain cases.
		+ Can be used to create more complex DOM structures.
	* Cons:
		+ Creates an actual text element, which may incur additional overhead due to its size and content.
2. **Appending a comment node**:
	* Pros:
		+ Creates a lightweight, minimalistic DOM node that is quickly removed.
		+ Does not create an actual text element, which can reduce overhead.
	* Cons:
		+ May not be as flexible or powerful as appending a text node.

**Library and purpose**

In both test cases, the `document.body` object is used to append nodes. This is a standard DOM API in most web browsers.

**Special JS feature or syntax (not applicable)**

There are no special JavaScript features or syntax used in this benchmark.

**Other alternatives**

If you wanted to compare these approaches, you could also consider:

* Appending a DOM element with a zero-width space character (`document.createElement('span').innerHTML = '\u200B';`)
* Using a library like jQuery to append nodes, which may introduce additional overhead due to its abstraction layer.

In summary, this benchmark is testing the performance difference between appending a text node and a comment node in JavaScript. The results can help determine whether one approach is more suitable for your specific use case depending on the trade-offs you're willing to make.
