# `useRefMounted`
Lifecycle hook that tracks if component is mounted. Returns a ref, which has a
boolean `.current` property.
## Usage
```jsx
import {useRefMounted} from 'react-use';
const Demo = () => {
const refMounted = useRefMounted();
useEffect(() => {
setTimeout(() => {
if (refMounted.current) {
// ...
} else {
// ...
}
}, 1000);
});
};
```
