Should you use dataset in 2026?

Using data-* attributes will be totally fine in all browsers, but instead of using elem.dataset.foo just use elem.getAttribute('data-foo'). A polyfill is available if you want terser syntax.

How to use it

<button data-product-id="42">Buy</button>
<script>
  const id = document.querySelector('button').dataset.productId;  // "42"
</script>
