#### Updating Data

```tsx
const items = [1, 2, 3, 4, 5];

function doReorder(event: CustomEvent) {
  // Before complete is called with the items they will remain in the
  // order before the drag
  console.log('Before complete', this.items);

  // Finish the reorder and position the item in the DOM based on
  // where the gesture ended. Update the items variable to the
  // new order of items
  this.items = event.detail.complete(this.items);

  // After complete is called the items will be in the new order
  console.log('After complete', this.items);
}
```
