Benchmark: document.createElement("audio") vs. blankAudioElement.cloneNode()

Tests:

blankAudioElement.cloneNode()
var audio = document.createElement("audio"); var output = new Array(1000); for (var i = 0; i < 1000; i++) output[i] = audio.cloneNode();
document.createElement("audio")
var output = new Array(1000); for (var i = 0; i < 1000; i++) output[i] = document.createElement("audio");

**Overview of the Benchmark**

The provided JSON represents a JavaScript microbenchmark test case created on MeasureThat.net. The benchmark compares two approaches for creating an audio element in HTML: using `document.createElement("audio")` and using `blankAudioElement.cloneNode()`.

**Test Case 1: Using `blankAudioElement.cloneNode()`**

In this test case, the script preparation code creates a new array of length 1000 and then clones 1000 times an existing audio element using `blankAudioElement.cloneNode()`. The purpose of creating multiple cloned copies is likely to measure the performance of cloning an audio element.

**Test Case 2: Using `document.createElement("audio")`**

In this test case, a new array of length 1000 is created and then for each iteration, a new audio element is created using `document.createElement("audio")`. The purpose of creating multiple audio elements in the same scope is likely to measure the performance of creating an individual audio element.

**Options Compared**

The two options compared are:

1. **Using `blankAudioElement.cloneNode()`**: This approach creates a cloned copy of an existing audio element, which may be more efficient in terms of memory allocation and creation time.
2. **Using `document.createElement("audio")`**: This approach creates a new audio element from scratch, which may require more resources and time.

**Pros and Cons**

* Using `blankAudioElement.cloneNode()`: Pros - potentially faster creation and cloning times due to reusing an existing element; Cons - if the cloned element is not used further, it will still consume memory.
* Using `document.createElement("audio")`: Pros - does not require cloning or reusing an existing element; Cons - may be slower due to the overhead of creating a new element from scratch.

**Library Usage**

In both test cases, no specific library is used. However, in the first test case, `blankAudioElement` seems to be an existing audio element that is being cloned, which suggests that it might be created elsewhere in the code or loaded from an external source (e.g., a library or a web page).

**Special JS Features/Syntax**

Neither of the benchmarked approaches uses any special JavaScript features or syntax.

**Other Alternatives**

If you were to create alternative test cases for this benchmark, you could consider exploring other approaches, such as:

* Using `HTMLAudioElement` instead of `Document.createElement("audio")`
* Creating an array of audio elements and then cloning them using `Array.prototype.map()`
* Using a library like jQuery or a custom implementation to measure the performance of creating multiple audio elements.

Keep in mind that these alternatives would require significant changes to the benchmark and may not accurately represent the original intent of the test cases.
