## DataSnapshot.hasChildren() method

Returns whether or not the `DataSnapshot` has any non-`null` child properties.

You can use `hasChildren()` to determine if a `DataSnapshot` has any children. If it does, you can enumerate them using `forEach()`<!-- -->. If it doesn't, then either this snapshot contains a primitive value (which can be retrieved with `val()`<!-- -->) or it is empty (in which case, `val()` will return `null`<!-- -->).

<b>Signature:</b>

```typescript
hasChildren(): boolean;
```
<b>Returns:</b>

boolean

true if this snapshot has any children; else false.
