# `useAsync`
React hook that resolves an `async` function or a function that returns
a promise;
## Usage
```jsx
import {useAsync} from 'react-use';
// Returns a Promise that resolves after one second.
const fn = () => new Promise((resolve) => {
setTimeout(() => {
resolve('RESOLVED');
}, 1000);
});
const Demo = () => {
const {loading, value, error} = useAsync(fn);
return (
<div>
{loading
? <div>Loading...</div>
: <div>Value: {value}</div>
}
</div>
);
};
```
## Reference
```ts
useAsync(fn, args?: any[]);
```
