HTML Preparation code:
<div id="header" > <script type="application/json"> { "links": [{ "label": "un", }, { "label": "deux", }], "listLinks": ["sdsf", "dssd"] } </script> </div> <div id="header2" data-props='{ "links": [{ "label": "un", }, { "label": "deux", }], "listLinks": ["sdsf", "dssd"] }' > </div>
Tests:
un
const headerDom = document.querySelector('#header'); const headerData = JSON.parse(headerDom.querySelector('script').innerHTML); console.log(headerData)
deux
const headerDom = document.querySelector('#header'); const props = JSON.parse(headerDom.getAttribute('data-props')); console.log(props)

**What is tested in the provided JSON?** The provided JSON represents a JavaScript microbenchmark created on MeasureThat.net. The benchmark tests two different approaches to parse and access data from an HTML document using JavaScript. **Options compared:** There are two test cases: 1. **Test Case 1 ("un")**: This test case uses `document.querySelector` to select the element with the ID "header", then parses the innerHTML of the script element inside that header to extract the JSON data. 2. **Test Case 2 ("deux")**: This test case uses `document.querySelector` to select the element with the ID "header", then accesses the `data-props` attribute of that element, which contains the same JSON data as in Test Case 1. **Pros and Cons:** * **Test Case 1 (un)**: + Pros: Easy to understand, simple syntax. + Cons: May be slower due to parsing the innerHTML of the script element, which can be complex HTML structure. * **Test Case 2 (deux)**: + Pros: Faster execution time since it directly accesses the `data-props` attribute, a known property of the element. + Cons: May require more expertise in accessing and manipulating DOM attributes. **Library/Functionality Used:** In both test cases, the `JSON.parse()` function is used to parse the JSON data from the HTML document. This is a built-in JavaScript function that parses a JSON string into a JavaScript object. **Special JS Features/Syntax:** None mentioned in this benchmark. **Other Considerations:** * The use of `data-props` attribute as a way to store and access data is a common pattern in web development, especially when working with complex HTML structures. * The `document.querySelector` method is used to select elements based on their ID or other attributes, which is an efficient way to navigate the DOM. **Alternatives:** If you wanted to run this benchmark, you could create similar test cases using JavaScript and a tool like MeasureThat.net. You could also consider alternative approaches, such as: * Using a library like jQuery to simplify DOM manipulation. * Optimizing the HTML structure to reduce parsing time for Test Case 1 (un). * Using a different method to access the data, such as storing it in a separate variable or using a more efficient data storage solution.
