Benchmark: performanceDom - MeasureThat.net

Script Preparation code:

const a = document.createElement('test');
        document.head.appendChild(a); // Append 'a' to the document body
        let string = 'This element contains <code>code</code>\n' + '<p><strong>and HTML tags</strong></p>`'

        // Update innerHTML with a larger content
        let start = performance.now();
        a.innerHTML = string;
        let end = performance.now();
        let diff = end - start;

        start = performance.now();
        a.innerText = string;
        end = performance.now();
        let diff2 = end - start;

        start = performance.now();
        a.textContent = string;
        end = performance.now();
        let diff3 = end - start;

        start = performance.now();
        a.outerHTML = string;
        end = performance.now();
        let diff4 = end - start;

        console.table({
            'innerHTML': diff,
            'innerText': diff2,
            'textContent': diff3,
            'outerHTML': diff4
        });

Tests:

innerHTML
const a = document.createElement('test'); document.head.appendChild(a); // Append 'a' to the document body let string = 'This element contains <code>code</code>\n' + 'and HTML tags`'; let start = performance.now(); a.innerHTML = string; let end = performance.now(); let diff = end - start; console.log(diff);
innerText
const a = document.createElement('test'); document.head.appendChild(a); // Append 'a' to the document body let string = 'This element contains <code>code</code>\n' + 'and HTML tags`'; let start = performance.now(); a.innerText = string; let end = performance.now(); let diff = end - start; console.log(diff);
textContent
const a = document.createElement('test'); document.head.appendChild(a); // Append 'a' to the document body let string = 'This element contains <code>code</code>\n' + 'and HTML tags`'; let start = performance.now(); a.textContent = string; let end = performance.now(); let diff = end - start; console.log(diff);
outerHTML
const a = document.createElement('test'); document.head.appendChild(a); // Append 'a' to the document body let string = 'This element contains <code>code</code>\n' + 'and HTML tags`'; let start = performance.now(); a.outerHTML = string; let end = performance.now(); let diff = end - start; console.log(diff);

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks, providing insights into the performance of various browsers and devices.

**Benchmark Definition**

The provided JSON represents a benchmark definition for a test case called "performanceDom". This benchmark tests the performance of four different properties on an HTML element: `innerHTML`, `innerText`, `textContent`, and `outerHTML`. The script preparation code creates a new HTML element, appends it to the document body, and initializes its text content with a large string containing HTML tags.

The benchmark measures the time taken by each property setter (or getter) to update the element's text content. Specifically:

* `innerHTML` sets the entire HTML content of the element.
* `innerText` sets only the text content of the element.
* `textContent` sets only the text content of the element, without HTML tags.
* `outerHTML` sets the entire HTML content of the element, including attributes and tags.

**Comparison of Options**

The benchmark compares the performance of these four options:

Pros and Cons:

1. **innerHTML**:
	* Pros: Simple and efficient, as it only updates the text content without modifying the HTML structure.
	* Cons: Can be slower due to the need to parse and update the entire HTML content.
2. **innerText**:
	* Pros: Faster than `innerHTML`, as it only updates the text content without parsing the HTML structure.
	* Cons: May not work correctly in all cases, especially when the element has attributes or other non-text content.
3. **textContent**:
	* Pros: Fast and efficient, as it only updates the text content without modifying the HTML structure or parsing attributes.
	* Cons: May not work correctly with certain HTML tags or attributes.
4. **outerHTML**:
	* Pros: Most accurate representation of the element's HTML content, including attributes and tags.
	* Cons: Can be slower due to the need to parse and update the entire HTML content.

**Library and Purpose**

In this benchmark, there is no explicit library used. However, the `performance.now()` function is used to measure the time taken by each property setter (or getter). This function is a built-in JavaScript method that returns the current timestamp in milliseconds.

**Special JS Features or Syntax**

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

**Other Alternatives**

If you're looking for alternative benchmarks or testing tools, some options include:

* Browserbench: A benchmarking tool specifically designed for web browsers.
* WebPageTest: A performance testing tool that measures the load times and responsiveness of websites.
* BenchmarkJS: A JavaScript benchmarking framework that allows you to create and run custom benchmarks.

Keep in mind that these alternatives may have different use cases, requirements, or features compared to MeasureThat.net.
