Benchmark: innerhtml vs removechild vs remove(my version)

HTML Preparation code:

<div id="container"></div>

Script Preparation code:

var node = document.getElementById('container');

for(var i = 0; i < 1; i++) node.appendChild(document.createElement('div'));

Tests:

innerHTML
var node = document.getElementById('container'); node.innerHTML = '';
removeChild
var node = document.getElementById('container'); while(node.firstChild) node.removeChild(node.firstChild)
remove
var node = document.getElementById('container'); while(node.firstChild) node.firstChild.remove()

Let's dive into the world of JavaScript microbenchmarks!

**Benchmark Definition**

The provided JSON represents a benchmark definition, which is a set of instructions that describes how to create and run a test case. In this case, we have three test cases:

1. `innerHTML`
2. `removeChild`
3. `remove` (a custom implementation)

Each test case has two parts: `Script Preparation Code` and `Html Preparation Code`.

**Script Preparation Code**

This code is executed before running each test case. It sets up a container element with an ID of "container" using JavaScript.

1. `var node = document.getElementById('container');`
	* This line retrieves the container element from the DOM.
	* The `document.getElementById` method returns a reference to the first element with the specified ID.
2. `for (var i = 0; i < 1; i++) node.appendChild(document.createElement('div'));`
	* This loop appends one empty `div` element to the container element.
	* The `appendChild` method adds a child node to the end of an element.

**Html Preparation Code**

This code is executed before running each test case. It creates a basic HTML structure with a container element:

1. `<div id="container"></div>`

The purpose of this code is to provide a minimal HTML environment for the test cases to execute in.

**Test Cases**

Each test case has a unique `Benchmark Definition` that describes how to run the test.

1. `innerHTML`
	* This test case clears the inner HTML of the container element using `node.innerHTML = '';`.
2. `removeChild`
	* This test case removes all child elements from the container element using `while (node.firstChild) node.removeChild(node.firstChild);`.
3. `remove` (custom implementation)
	* This test case uses a custom implementation to remove all child elements from the container element.

**Library**

The only library used in this benchmark is JavaScript's built-in DOM API (`document.getElementById`, `appendChild`, `removeChild`, etc.).

**Special JS Feature or Syntax**

None of the test cases use any special JavaScript features or syntax, such as async/await, promises, or arrow functions.

**Pros and Cons of Different Approaches**

Here are some pros and cons of each approach:

1. `innerHTML`:
	* Pros: Simple, easy to implement.
	* Cons: May not be the most efficient way to clear an element's content.
2. `removeChild`:
	* Pros: More efficient than using `innerHTML`, as it only removes child nodes.
	* Cons: Requires iterating over all child nodes, which can be slow for large datasets.
3. `remove` (custom implementation):
	* Pros: Customizable and potentially more efficient than the built-in methods.
	* Cons: Requires implementing a custom removal algorithm, which may add complexity.

**Other Alternatives**

Some alternative approaches to removing child elements from an element include:

1. Using a library like jQuery or React, which provide optimized DOM manipulation functions.
2. Using a CSS-based approach, such as using `transform` or `opacity` properties to hide the content.
3. Using a JavaScript framework or library that provides built-in support for efficient DOM updates.

However, these alternatives may add additional dependencies or complexity to the benchmark, and may not be suitable for all use cases.
