Prefer explicit role property in HTML tags JS-0764
Performance
Minor
Some HTML elements have native semantics that are implemented by the browser. This includes default/implicit ARIA roles. Setting an ARIA role that matches its default/implicit role is redundant since it is already set by the browser.
Bad Practice
<button role="button" />
<img role="img" src="foo.jpg" />
Recommended
<div />
<button role="presentation" />
<MyComponent role="main" />
