Benchmark: JQuery new div element with class - 1k reps #2

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); newNode.className = [].slice.call(arguments).join(' '); return $(newNode); } while(true) { n++; list.push(newDiv("test")); if(n===1000) break; }
Jquery - direct + class #2
var list = [], n = 0; var newDiv = function(){ return $('<div>',{class:"test"}); } while(true) { n++; list.push(newDiv()); if(n===1000) break; }

**Overview**

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks, comparing different approaches to measure their performance. The provided JSON data represents two benchmark definitions and three test cases.

**Benchmark Definition**

The Benchmark Definition JSON contains metadata about the benchmark, including its name, description, script preparation code, and HTML preparation code. In this case:

* The benchmarks are focused on creating new DOM elements with a specific class using jQuery.
* The scripts use different approaches to create the elements: direct creation (` $('<div>' or '<div>')`), cloning an existing element (`document.createElement('div').cloneNode(false)`), and concatenating strings to set the class.

**Options Compared**

The three test cases compare the following options:

1. **Direct Creation**: Creating a new DOM element directly using jQuery's `$` function, which sets the `class` attribute.
2. **CloneNode + Class**: Cloning an existing `<div>` element and then setting its `className` attribute using the `join()` method.
3. **Direct + Class #2**: Similar to Direct Creation, but with a different way of concatenating strings to set the class (not shown in the JSON data).

**Pros and Cons**

Here's a brief summary of the pros and cons of each approach:

* **Direct Creation**:
	+ Pros: Fast and concise.
	+ Cons: May not be compatible with older browsers or specific use cases where `class` is not supported.
* **CloneNode + Class**:
	+ Pros: Can be more flexible than direct creation, as it allows for dynamic class names.
	+ Cons: May incur additional overhead due to cloning the element and setting its class.
* **Direct + Class #2**: (Not shown in JSON data) - likely a variant of Direct Creation with some modifications.

**Library and Syntax**

None of the test cases use external libraries beyond jQuery, which is already included in the HTML preparation code. The syntax used is standard JavaScript, with no special features or syntax mentioned.

**Other Considerations**

When running these benchmarks, it's essential to consider:

* Browser compatibility: Different browsers may have varying levels of support for different DOM elements and APIs.
* Performance caching: Some approaches (like cloning) might incur additional overhead due to performance caching mechanisms.
* Use case specificity: The chosen approach should be suitable for the specific use case or application.

**Alternatives**

If you're interested in exploring alternative approaches, some options could include:

* Using a different library or framework that provides similar functionality.
* Employing server-side rendering or pre-compilation techniques to reduce DOM creation overhead.
* Utilizing WebAssembly or other low-level optimizations for better performance.
