Benchmark: template vs div (fixed 2)

Script Preparation code:

function template(html) {
  var t = document.createElement('template');
  t.innerHTML = html;
  return t.content.firstChild;
}

function div(html) {
  var t = document.createElement('div');
  t.innerHTML = html;
  return t.firstChild;
}

var html = '<div><div class="col-md-1"></div><div class="col-md-4"><a></a></div><div class="col-md-1"><a><span class="glyphicon glyphicon-remove" aria-hidden="true" /></a></div><div class="col-md-6" /></div>';

Tests:

Template
template(html).cloneNode(true);
Div
div(html).cloneNode(true);

**Overview**

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks. The provided JSON represents a benchmark definition, which tests the performance of two different approaches: using a `template` element versus a regular `div` element.

**Benchmark Definition JSON**

The benchmark definition JSON contains:

* `Name`: The name of the benchmark, which is "template vs div (fixed 2)".
* `Description`: An empty description field, indicating that no detailed description is provided for this benchmark.
* `Script Preparation Code`: A JavaScript code snippet that defines two functions: `template(html)` and `div(html)`. Both functions create an element from the provided HTML string and return its first child node. The `template` function uses a `<template>` element, while the `div` function uses a regular `<div>` element.
* `Html Preparation Code`: An empty field, indicating that no additional HTML preparation code is required.

**Individual Test Cases**

The benchmark definition includes two individual test cases:

* `"Benchmark Definition": "template(html).cloneNode(true);",`
* `"Benchmark Definition": "div(html).cloneNode(true);,"`

These test cases compare the performance of cloning a node from both the `template` and `div` approaches.

**Options Compared**

The benchmark compares the performance of two options:

1. **Template Element**: Using a `<template>` element to create an element from the provided HTML string.
2. **Regular Div Element**: Using a regular `<div>` element to create an element from the provided HTML string.

**Pros and Cons of Each Approach**

* **Template Element:**
	+ Pros:
		- Can be used to create an isolated, mutable copy of an element without affecting the original document.
		- May provide better performance due to optimized DOM creation and manipulation.
	+ Cons:
		- Not widely supported in older browsers or mobile devices.
		- May require additional setup and configuration.
* **Regular Div Element:**
	+ Pros:
		- Widely supported in modern browsers and mobile devices.
		- Simple to implement and use.
	+ Cons:
		- May not provide the same level of isolation as a `template` element.
		- Can be slower due to DOM creation and manipulation overhead.

**Library and Purpose**

The benchmark uses the `cloneNode(true)` method, which is a part of the DOM API. The purpose of this method is to create a deep copy of an element, including its children and attributes, without losing any data.

**Special JS Feature or Syntax**

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

**Other Alternatives**

If you need to compare performance between creating elements using `template` and `div`, there are other alternatives:

* Using a virtual DOM library like React or Angular, which optimize DOM creation and manipulation.
* Using a library like jQuery, which provides an abstraction layer for DOM manipulation.
* Implementing custom optimization techniques, such as memoization or caching.

Keep in mind that these alternatives may have different trade-offs in terms of performance, complexity, and compatibility with different browsers and devices.
