## DataSnapshot.child() method

Gets another `DataSnapshot` for the location at the specified relative path.

Passing a relative path to the `child()` method of a DataSnapshot returns another `DataSnapshot` for the location at the specified relative path. The relative path can either be a simple child name (for example, "ada") or a deeper, slash-separated path (for example, "ada/name/first"). If the child location has no data, an empty `DataSnapshot` (that is, a `DataSnapshot` whose value is `null`<!-- -->) is returned.

<b>Signature:</b>

```typescript
child(path: string): DataSnapshot;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  path | string | A relative path to the location of child data. |

<b>Returns:</b>

[DataSnapshot](./database.datasnapshot.md)
