isSameById

NOTE: Doesn't compare objects for equality; only their id


item1

item2

fallbackGetId

boolean

_key

Interface for types that we can automatically extract a unique identifier from.

To confirm to the interface provide a `_key` property or getter.

[ViewModelFactory](doc:viewModelFactory) conforms to this so anything that expects an Identifiable
will accept a ViewModel.

Implementing this can save you having to pass explicit functions to identify an item in other parts of the system
(eg. for [AsyncChoices](doc:AsyncChoices) or [useAsyncValue](doc:useAsyncValue))


	Parameter	Type
*	item1	Identifiable\|any
*	item2	Identifiable\|any
