const App = () => {
return (
<div>
<h2>Hello world</h2>
</div>
);
};
export default App;

module.exports = {
rules: {
"react/display-name": "off",
}
}
We can also disable the rule for a single file by adding the following comment at the top of the file.
/* eslint-disable react/display-name */
// ... your code here
