ElementInternals.ariaChecked

The ariaChecked property of the ElementInternals interface reflects the value of the aria-checked attribute, which indicates the current "checked" state of checkboxes, radio buttons, and other widgets that have a checked state.

Note: Setting aria attributes on ElementInternals allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the Accessibility Object Model explainer.
