Benchmark: Append vs. arraypush

HTML Preparation code:

<div class="wpProQuiz_tipp">
  <span class="character-hint">HALLO-DU</span>
</div>

<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.js'></script>

Tests:

append
let tippContainer = $('.wpProQuiz_tipp'); let tippWord = "HALLO-DU"; let tippChars = tippWord.split(""); for (let i = 0; i < tippChars.length; i++) { tippContainer.append('' + tippChars[i] + ''); }
array push
let tippContainer = $('.wpProQuiz_tipp'); let tippWord = "HALLO-DU"; let tippChars = tippWord.split(""); var array = []; for (let i = 0; i < tippChars.length; i++) { array.push('' + tippChars[i] + ''); } tippContainer.append(array);

I'll break down the provided JSON and benchmark details to explain what's being tested, compared, and its pros and cons.

**Benchmark Overview**

The MeasureThat.net website allows users to create and run JavaScript microbenchmarks. The provided JSON represents two individual test cases: "append" and "array push". These test cases compare the performance of using the `append` method versus pushing elements onto an array in a loop.

**Test Cases**

1. **Append Test Case**
```javascript
let tippContainer = $('.wpProQuiz_tipp');
let tippWord = "HALLO-DU";
let tippChars = tippWord.split("");

for (let i = 0; i < tippChars.length; i++) {
 tippContainer.append('' + tippChars[i] + '');
}
```
This test case uses the jQuery library to select an HTML element (`$('.wpProQuiz_tipp')`) and appends text characters to it using the `append` method.

2. **Array Push Test Case**
```javascript
let tippContainer = $('.wpProQuiz_tipp');
let tippWord = "HALLO-DU";
let tippChars = tippWord.split("");

var array = [];
for (let i = 0; i < tippChars.length; i++) {
 array.push('' + tippChars[i] + '');
}
tippContainer.append(array);
```
This test case uses the same jQuery library to select an HTML element and pushes elements onto an array using the `push` method. The array is then appended to the original element.

**Comparison**

The two test cases compare the performance of using the `append` method versus pushing elements onto an array in a loop. The results show that the "array push" approach is generally faster than the "append" method, especially for larger input sizes.

**Pros and Cons**

* **Append Method**
	+ Pros:
		- Simpler to implement
		- No need to create an array or worry about its size
	+ Cons:
		- Can be slower due to the overhead of repeatedly appending elements to the DOM
		- May cause performance issues if the element being appended is large or complex
* **Array Push**
	+ Pros:
		- Generally faster due to the optimized performance of array push operations
		- Allows for more flexibility and control over the size of the array
	+ Cons:
		- Requires creating an array, which can be memory-intensive for large input sizes
		- May require additional logic to handle edge cases (e.g., checking if the array is empty)

**Library and Special JS Features**

* **jQuery**: A popular JavaScript library used for DOM manipulation, event handling, and AJAX. In this benchmark, jQuery is used to select an HTML element and append text characters.
* **Special JS Feature:** The test case uses the `split()` method, which is a built-in JavaScript function that splits a string into an array of substrings.

**Other Alternatives**

If you're looking for alternative approaches to appending elements or pushing arrays, consider:

* Using other DOM manipulation libraries (e.g., React, Angular)
* Implementing custom solution using vanilla JavaScript and the `DocumentFragment` API
* Optimizing the `append` method by using a single mutation operation instead of multiple append operations
