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. Signature: ```typescript child(path: string): DataSnapshot; ``` ## Parameters | Parameter | Type | Description | | --- | --- | --- | | path | string | A relative path to the location of child data. | Returns: [DataSnapshot](./database.datasnapshot.md)
