What does the dataset property allow you to do?

Access all inline styles
Access custom data attributes
Modify the element's DOM properties
Retrieve standard HTML attributes

The correct answer is: Access custom data attributes

The dataset property is used to access custom data attributes in HTML elements. Specifically, it allows you to work with data attributes that are prefixed with "data-", such as data-user-id or data-role. These attributes are designed to store extra information that doesn't affect the rendering of the element. When you use the dataset property in JavaScript, it automatically converts these attributes into a convenient JavaScript object, making it easy to read from and write to these custom attributes. For instance, if you have an element with a data attribute like `data-theme="dark"`, you can access this value through `element.dataset.theme`, which simplifies the process of handling HTML elements with custom data. This feature is particularly useful in web applications that require dynamic behavior and interactivity, as it allows developers to associate additional information with HTML elements without cluttering the markup with extra classes or IDs.
