 ### Array Bindings
 
-Each record in the bound array will contain a `_key` property which specifies the key where the record is stored. So if you have data at `/items/-Jtjl482BaXBCI7brMT8/`, the record for that data will have a `_key` of `"-Jtjl482BaXBCI7brMT8"`.
+Each record in the bound array will contain a `.key` property which specifies the key where the record is stored. So if you have data at `/items/-Jtjl482BaXBCI7brMT8/`, the record for that data will have a `.key` of `"-Jtjl482BaXBCI7brMT8"`.
 
-If an individual record's value in the database is a primitive (boolean, string, or number), the value will be stored in the `_value` property. If the individual record's value is an object, each of the object's properties will be stored as properties of the bound record. As an example, let's assume the `/items/` node you bind to contains the following data:
