Luckily, there's an easy way to label these values, using the `useDebugValue()` hook to create a custom `useStateWithLabel` hook: ```jsx const useStateWithLabel = (initialValue, label) => { const [value, setValue] = useState(initialValue); useDebugValue(`${label}: ${value}`); return [value, setValue]; }; const Counter = () => { const [value, setValue] = useStateWithLabel(0, 'counter'); return (

{value}

); }; ReactDOM.createRoot(document.getElementById('root')).render( ); // Inspecting `Counter` in React developer tools will display: // StateWithLabel: "counter: 0" ``` This hook is obviously meant mainly for development, but it can also be useful when creating React component or hook libraries. Additionally, you can easily abstract it in a way that the label is ignored in production builds. An example would be exporting a hook that defaults back to `useState()` when building for a production environment.
