[Home](./index.md) > [@firebase/database](./database.md) > [DataSnapshot](./database.datasnapshot.md) > [hasChildren](./database.datasnapshot.haschildren.md) ## 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`). Signature: ```typescript hasChildren(): boolean; ``` Returns: boolean true if this snapshot has any children; else false.
