# `useTween`
React animation hook that tweens a number between 0 and 1.
## Usage
```jsx
import {useTween} from 'react-use';
const Demo = () => {
const t = useTween();
return (
<div>
Tween: {t}
</div>
);
};
```
## Reference
```ts
useTween(easing?: string, ms?: number, delay?: number): number
```
Returns a number that begins with 0 and ends with 1 when animation ends.
