 A better way to structure our data in Reflex is to use a class to represent a user. This way we can access the data using attributes i.e. `user.name`, `user.email`.
 
-In Reflex when we create these classes to showcase our data, the class must inherit from `rx.Base`.
-
-`rx.Base` is also necessary if we want to have a state var that is an iterable with different types. For example if we wanted to have `age` as an `int` we would have to use `rx.base` as we could not do this with a state var defined as `list[list[str]]`.
+In Reflex when we create these classes to showcase our data, we can use dataclasses.
 
 The `show_user` render function is also updated to access the data by named attributes, instead of indexing.
