Example:
<article id="post" data-author="Jay" data-published="2024-05-04"> <h2>Custom Data Attributes</h2> <p>Data stored in this element can be used by scripts.</p> </article> |

let article = document.querySelector('#post'); console.log(article.dataset.author); // Outputs: Joy console.log(article.dataset.published); // Outputs: 2024-05-04 |

They also improve the functionality and interaction of HTML elements with CSS and JavaScript. When used properly, they can significantly improve web development projects' performance, maintainability, and efficiency.
