## When To Use
To display a notification message at any of the four corners of the viewport. Typically it can be
used in the following cases:
- A notification with complex content.
- A notification providing a feedback based on the user interaction. Or it may show some details
about upcoming steps the user may have to follow.
- A notification that is pushed by the application.
## API
- `notification.success(config)`
- `notification.error(config)`
- `notification.info(config)`
- `notification.warning(config)`
- `notification.warn(config)`
- `notification.close(key: String)`
- `notification.destroy()`
The properties of config are as follows:
| Property | Description | Type | Default |

```js
notification.config({
placement: 'bottomRight',
bottom: 50,
duration: 3,
});
```
