is it documented somewhere how a kotlin class looks like in js? for example if i have a `data class K(val a:String, val b:String)`and i instantiate it as K("first", "second"), then cast it to dynamic and pass it to a javascript method, does it look like this: `{a: "first", b:"second"}`(possibly with more fields) ?

If you need plain object like in example - use #serialization

If you need public contract for data class (performance optimization for example) you can use external interface

Data.kt

i have kotlin data classes that i serialize to json on the server and then i want to use it in a react app that is mostly typescript. so if i deserialize it to a kotlin object i have to serialize it again if i want to use it in typescript

[christophsturm]

so i was wondering if i instead just convert the json to typescript object.

after some experimenting it seems your suggestion of a data class that implements an external interface is exactly what i needed. thanks!
