sorry if this question has already been answered, but I'm using the Kotlin/Js inspection plugin and in the generated Kotlin/React project it is saying that the data class which extends state should be an external interface. The most up to date docs show it as a data class. Is the inspection plugin lagging behind the most up to date docs or should it really be an external interface?

Plain JSO is preferred, for props and state
Otherwise behaviour is unexpected

Also function components are preferred (future is here)

Ok thanks. Whats the current recommended way for creating a plain js object in Kotlin?

In most cases it would be hidden, like here:
```attrs {
   q = 10
}```
For other cases - `jso` factory method:
```val props: MyProps = jso {
    q = 10
}```
Also you can create custom factory method, when you have many required properties
