Is there any meaningful difference between: ```//...

# javascript

Is there any meaningful difference between:

// kt
external interface Dress {
  val color: Int
} 
val dress: Dress = jso { color = ... }

and

// ts

const dress: Dress = { color: ... }

I'm noticing that the first is failing the serialization with fast-json-stringify, while the second is passing it. If I stringify and parse the result with JSON.parse(JSON.stringify(dress)) then it passes the serialization successfully 🤔 Wondering if there's something in the instance created by jso that is preventing the serialization

No difference expected

Possible root causes:
• Invalid schema
• Non-external interface in jso created (looks like this)

I managed to fix it and ultimately turned the external interface into a data class. The fact that my external interface was implementing another external interface was preventing it from being serialized correctly on the JS side

external interface Base

external interface Derived: Base {
  var property: String
}

val obj = jso { property = "" } // this fails to be serialized with fast-json-stringify

data class Derived2(val property: String) : Base
val obj2 = Derived2("") // this also fails to be serialized

data class Derived3(val property: String)
val obj3 = Derived3("") // this succeeds
