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.
The default options for this rule allow an implicit role of navigation to be applied to a nav element as is advised by w3. The options are provided as an object keyed by HTML element name; the value is an array of implicit ARIA roles that are allowed on the specified element.
{
'jsx-a11y/no-redundant-roles': [
'error',
{
nav: ['navigation'],
},
}
```jsx
jsx
<button role="button" />
<img role="img" src="foo.jpg" />
