Benchmark: JQuery new div element with class - 1k reps

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.js'></script>

Tests:

JQuery - direct + class
var list = [], n = 0; var newDiv = function(){ return $('<div class="test">'); } while(true) { n++; list.push(newDiv()); if(n===1000) break; }
JQuery - cloneNode + class
var list = [], n = 0, node = document.createElement('div'); var newDiv = function(){ var newNode = node.cloneNode(false); node.className = [].slice.call(arguments).join(' '); return $(node); } while(true) { n++; list.push(newDiv("test")); if(n===1000) break; }

Let's break down the provided JSON and explain what's being tested, compared, and discussed.

**Benchmark Definition**

The benchmark definition provides two ways to create new DOM elements with jQuery:

1. **Direct + class**: This approach uses the `$` function directly to create a new `<div>` element with a class of "test".
2. **CloneNode + class**: This approach creates a new `<div>` element using `document.createElement`, clones it, and then sets its class using `node.className`.

**What's being compared**

The benchmark is comparing the performance of these two approaches:

* **Direct + class**: Creating a new DOM element with jQuery's `$` function and setting its class.
* **CloneNode + class**: Creating a new DOM element, cloning it, and then setting its class.

**Pros and Cons**

Here are some pros and cons for each approach:

1. **Direct + class**:
	* Pros:
		+ Faster creation of DOM elements ( likely due to the optimized jQuery code)
		+ Less overhead compared to CloneNode
	* Cons:
		+ May not be as flexible or customizable as other approaches
2. **CloneNode + class**:
	* Pros:
		+ More flexible and customizable, as it allows for additional DOM element properties
		+ Can be useful in scenarios where multiple copies of the same element are needed
	* Cons:
		+ Slower creation of DOM elements due to the CloneNode process

**Library**

In both benchmark definitions, jQuery is used as a library. Its purpose is to simplify DOM manipulation and provide an easy-to-use API for creating and interacting with web pages.

**Special JS feature or syntax**

There isn't any special JavaScript feature or syntax being tested in this benchmark. The focus is on comparing the performance of two approaches to create new DOM elements with jQuery.

**Other alternatives**

If you're interested in exploring alternative ways to create new DOM elements, here are some options:

1. **Vanilla JavaScript**: You can use `document.createElement` directly to create a new `<div>` element without any library.
2. **React or ReactDOM**: If you're building a React-based application, you can use the `createElement` function from `react-dom`.
3. **VUE.js**: For VUE.js applications, you can use the `$createElement` function.

Keep in mind that each of these alternatives has its own trade-offs and performance characteristics, which may not be directly comparable to the jQuery-based approaches tested in this benchmark.
